A Report Full of N/A: What Billiards Teaches Sports Analytics About Saying 'Insufficient Data'

A report running nine sections long. Each section carried a table. And every cell in every table held the same identical line: "N/A – insufficient information."

The first section asked which discipline was being analysed. The answer sat on the top row: undisclosed. The second asked about players — how many titles, how many century breaks, how many maximums. Insufficient information. The third asked about tournament format, prize structure, ranking status. Insufficient information. It continued that way down to the ninth, where the billiards industry supply-chain table sat equally empty, every cell stamped with the same repeated phrase.

The interesting part sits on the final line. Instead of filling the gaps with speculation, the author chose a different path: reject the input, request a re-run of the source-data step, and file the whole incident as a pipeline failure, detached from any professional conclusion.

I read that document four times in two days. The first time out of habit, curious how an automated analysis process handles a void. By the fourth reading I understood I was holding one of the most honest sports documents I had encountered in years.

"Numbers do not tell the whole story, but they know where the story begins." When the numbers are entirely absent, the story cannot begin anywhere at all. That closing line was a rare confession inside my industry: here, I do not know — and I will not perform certainty for an audience.

Billiards carries the thinnest data layer of any regularly broadcast sport. Football has PPDA, expected goals, and positional tracking running fifteen times per second. Billiards has what? Century breaks, maximums, pot success rate, safety success rate, and average shot time — AST. That is close to the complete inventory.

CueTracker, the community-run database, is the most serious reference available. Even there you will not find real-time ball-position data, cue-ball speed, or the number of seconds a player stands motionless before the decisive shot in frame thirty-one. The things that decide matches sit outside the spreadsheets.

In Vietnam the gap runs wider still. In September 2026, Bao Phuong Vinh won the three-cushion carom world title in Ankara, beating Tran Quyet Chien in an all-Vietnamese final — a landmark the sport had never seen here. Try to find a public dataset logging his average per-innings across that tournament. It does not exist, or it survives as a few lines in a short news item before vanishing.

That is the paradox of the sport we cover. A country with a world champion, thousands of billiard halls open every night, and a generation of young cueists raised on YouTube — yet not one decent database to tell that story in numbers. Community memory substitutes for data, and memory always favours whoever is telling the story.

The 2026-26 professional snooker season is passing its midpoint. This is the stage when people write most carelessly: the rankings have settled, Crucible places remain undecided, and every week a nineteen-year-old rattles off three straight centuries and sets social media alight. The pressure to hold an opinion every single day pushes the entire media pack toward filling gaps with anecdote.

I was once part of that. In 2026, hosting a digital tactics show for a new online sports channel, I used tracking data to show Liverpool had recovered the ball nine times inside Manchester City's defensive third, far above the league average. A former international player mocked me publicly. I posted a heat map and a screenshot rather than arguing. The lesson I kept was not about winning an argument. It was that a chart only holds value when I state how many matches it came from — and what it cannot answer.

Nine years later, reading that empty report, I realised the whole industry has forgotten that principle.

The core point sits here: an empty data cell and a clean data cell are two entirely different states. Yet in most sports reporting they are presented identically — as silence.

That silence is where the danger breeds. When numbers are missing, a writer has two honest options: state clearly what is missing, or stay quiet. The industry picks a third: write from feeling, then dress it in the costume of analysis.

Take the biggest billiards story of the past two years. On 5 May 2026, Zhao Xintong won the World Snooker Championship, beating Mark Williams 18-12 in a final spread across two days at the Crucible. Not long before, Zhao had served a twenty-month suspension in the match-fixing affair that saw ten Chinese players sanctioned in 2026, with lifetime bans for Liang Wenbo and Li Hang. He returned through the amateur route, holding no professional ranking, forced to qualify from outside the Crucible.

Open any ranking database in April 2026 and search his name. The cell returns blank. No ranking. No accumulated points. No record of major-tournament results over the previous three years. By pure spreadsheet logic, he was an unknown not worth backing.

He won anyway.

That is a perfect illustration of how an empty cell is not a negative verdict. It is only an empty cell. What made the difference lived outside the data column entirely: the feel for the ball after twenty months away, the strange calm of a man who had already lost everything, and the capacity to endure four days of play inside a hushed Crucible against a three-time world champion.

I went back and watched Zhao's qualifying footage in Sheffield. What struck me was not the long pots. It was the time he spent standing at the table between shots — noticeably longer than any rival in his section of the draw. No system logs that metric in untelevised qualifiers. AST exists only in televised matches. Which means the entire record of the most important stretch of the eventual champion's campaign was discarded before anyone could capture it.

Another case, closer to the question of uncertainty. In the middle of the pandemic in 2026, the World Championship still took place at the Crucible, from 31 July to 16 August, with a near-empty arena and a very small pilot audience admitted for the final. Ronnie O'Sullivan beat Kyren Wilson 18-8. It was a rare natural experiment: same table, same rulebook, same field of players, with the entire acoustic layer of the arena removed.

"The pandemic did not kill football; it exposed the tactical skeleton." In billiards it exposed something else: how much of a player's record comes from the player, and how much comes from the room. With no coughing, no shuffling chairs, no sigh after a miss, some cueists played markedly faster. Others collapsed. No column in any official statistical table records that difference, though it decides careers.

I spent years sitting in a major broadcaster's analysis room, and I know why these gaps persist. Recording data costs money. Recording it at qualifiers nobody watches costs money for nothing. Sponsors pay for images, for clean scoreboards, for moments cut into short clips. Nobody pays for a column that only somebody three years later will need.

"Before you pick a team, read what people call them." In billiards this is almost a rule of nature. Ronnie O'Sullivan has been "The Rocket" since he was a boy, and the name describes him better than any speed analysis. Mark Williams is "The Welsh Potting Machine." John Higgins is "The Wizard of Wishaw," sorcerer of a small town outside Glasgow. Mark Selby is "The Jester from Leicester" — a name that announces he will smile, slow the match down, and strangle opponents with patience. And Zhao Xintong is known to fans as "The Cyclone."

Notice: no data department invented any of these. The crowd did, and the crowd got them right. It is the most efficient compression algorithm the sport possesses — one phrase carrying style, tempo, hometown, and fate. Fan language tends to read a player's identity correctly before the spreadsheet is updated.

But a nickname only works if people say it properly. I learned that through a professional scar. In 2026, commentating live on the France-Uruguay quarter-final at the World Cup, I mispronounced defender Jose Giménez's name three times in the first half. Viewers complained, the broadcaster warned me, and I apologised publicly. For a month afterwards I rewatched Uruguay's entire tape library purely to memorise how each name is spoken.

Since then, every piece I write on international billiards carries a pronunciation note. "Zhao Xintong" gets a phonetic guide. "Kyren Wilson" — Kai-ren, not Ki-ren, an error half the world's commentators still make weekly. It is a small thing, but it belongs to the same family as logging untelevised qualifiers: work nobody pays for, without which the final product is wrong.

"The thicker the database, the more the story must be told with human ears, not machine eyes." I have spent long stretches trying to move cross-sport models into billiards. When competitions stopped in 2026, I launched an online talk series, inviting fifteen analysts from six different sports — twelve episodes, roughly 2.3 million views. In one episode I placed cricket's powerplay phase beside average shot time in billiards. Both are speed metrics, and both fail identically when used to predict outcomes.

That failure is structural. A cueist with a low AST is not automatically more dangerous. He simply decides faster. In billiards, deciding fast and deciding correctly are two separate abilities, often inversely related, and no index captures the trade-off. Football measures it through situational success probability. Billiards has nothing.

Which brings me to the 2026 case. When the governing body announced sanctions against ten Chinese players in June, what collapsed was not merely a handful of careers. It was trust in the entire data architecture of the sport. Every century, every title, every pot-success figure belonging to a convicted player became suspect in public view. A record contaminated at the root leaves no upper column with value — which is precisely why data integrity carries such a price.

Zhao Xintong, returning from that very affair, stands as the counter-proof. His file was stained, then loaded with a ranking void, and in the end he still lifted the trophy. Had I read only the data, I would have written him wrong from beginning to end.

There is a temptation every sports writer fights daily. When a dataset is empty, the fastest route is to pivot to emotion. Emotional writing is always correct because it is immune to verification. It is also always cheap. And it destroys the very sport it claims to celebrate, by turning cueists into film characters rather than technical workers.

My counter-intuitive angle is this: the biggest problem in billiards today is not missing data. It is excessive confidence in what already exists.

The industry habitually reads a few small numbers and tells a large story. One maximum at an invitational is not proof of form. Three centuries across two days is not the mark of a champion. The sample is too small, and this sport carries one of the highest variances in individual head-to-head competition. A table slightly off level, a ball slightly slicker than standard, a draught from the air conditioning — any of these wipes out the predictive value of three months of figures.

Second, the sport takes pride in being hard to measure. There is a traditional Crucible pride: you cannot measure nerve, you cannot measure a cold head in the deciding frame. That pride is true, and it doubles as the excuse that has stopped the industry from ever building a proper data system. The truth is nobody has yet been willing to spend the money to find out.

Third, and most overlooked: whole categories of things nobody measures at all. How many billiard halls open each night in Vietnam. How many children under fifteen have access to a competition-standard table. How many clubs employ a certified coach. We measure a pot into the corner pocket and not the hall that taught the pot. That hole is larger than every technical gap, and no table on earth records it.

One more risk deserves to be named aloud. When a dataset is empty, it does not produce neutrality. It produces a power vacuum, and that vacuum is filled by whoever has the strongest incentive. In betting, the vacuum is filled with odds. In media, it is filled with anecdote. Neither serves the sport.

Where should the process go instead? A nine-section report full of N/A sounds like failure. I would call it a template. It acknowledges three distinct layers of not knowing. Layer one: no data exists, and that is stated plainly. Layer two: weak signals exist, carrying low confidence, and they are labelled as such. Layer three: strong signals exist, with source and date, verifiable again. Most sports reporting blends all three into a single undifferentiated voice.

The one line worth learning from that document is the one readers scroll past: when information is insufficient, the correct professional action is to reject the input. No compromise, no guessing, no filling in. Across twenty-seven years of press rooms, I have met very few sports editors with the nerve to tell their audience: we do not yet have enough to conclude.

Yet that is exactly what Vietnamese readers deserve. They follow billiards every night. They know every cueist in the carom scene and every snooker champion. They remember precisely how Bao Phuong Vinh beat Tran Quyet Chien in Ankara in 2026, down to individual shots that international databases sometimes log wrongly or omit altogether. Knowledge like that should not be answered with confident, hollow analysis.

"A major event does not end when the whistle sounds; it begins when the lights snap off." For billiards, the lights snap off every time a broadcaster stops recording at the qualifiers, every time an Asian tournament finishes with nobody archiving the data, every time a young champion disappears from the rankings because no one was assigned to keep them current.

The next leap for this industry will not come from measuring more. It will come from honestly logging what has not yet been measured — a catalogue of gaps, maintained as a normal part of the job. Whoever keeps that catalogue will tell the story of the next twenty years, because the best storytellers are always those who know exactly where they have not yet looked.

If one thing travels with me from that report full of N/A, it is this: a gap correctly named is worth more than a conclusion invented. In billiards, as in every other sport, people still lose because they trusted a number that was written into a place meant to stay blank.
