Vietnamese Billiards and the Data Void: When the Tracking Sheet Has Not a Single Line

Saturday night, after the last match at a billiards club in Binh Duong, I opened the tracking folder of a nineteen-year-old cueist. The cover carried the tournament name, the player's name, the date. Inside, blank: no average per inning column, no safety success rate, no run count, not even a line stating whether the event was three-cushion carom or nine-ball pool. A six-week season compressed into four handwritten words: win, loss, win, loss.

I sat with that sheet for a long while. The tracking sheet was not wrong in any cell, because it had never had a cell in which to be wrong. In my line of work this is the worst kind of data: an empty sheet that looks like a conclusion but is really a silence.

World billiards runs as four separate data worlds. Snooker has CueTracker recording every break, every century, potting percentages by season. Pool has FargoRate, ranking players by win probability. Three-cushion carom has UMB scoring systems and continental federations, where average per inning is a survival metric. Those systems do not measure in the same unit and cannot be compared directly.

Vietnam sits exactly at the intersection of all three. Billiards clubs exist in nearly every district of the major cities. SEA Games 31, hosted by Vietnam in 2026, put billiards into the official competition programme, with live television and full stands. But when the match ends, most of the data stays in the referee's notebook, or in the memory of whoever was watching.

I follow billiards from an odd position. Since 2026 I have commentated snooker for VTC, living through nearly the whole Davis and Hendry era, so I am used to a match being retold break by break. Since 2026 I have worked as a data consultant for a football club in Binh Duong. Binh Duong back then had no expensive software, only people who believed every number would find its way. In billiards that lesson still holds, except that here there is not yet a number to believe. I am the one who stays with the spreadsheet after the lights go out — you may call that a job, I call it a calling.

In any billiards analysis, the blocker sits at the very first step: locking down the discipline. Three-cushion carom is played on a pocketless table, scored per inning, where attack and safety are two faces of the same calculation. Nine-ball pool has pockets and depends on break quality and the position play that follows. Snooker has fifteen reds and an entire break-building system. Chinese 8-ball and English billiards are yet other problems. In Vietnam, all of it collapses into one word: billiards. The club I visited last week had three carom tables and six pool tables, one drinks counter, one price list. "Do you play billiards?" is a question that cannot answer anything. An analysis that cannot lock down the discipline cannot analyse anything, and that is the first blocker rather than a minor detail.

Player data is the next layer. For three-cushion carom I need average per inning, innings per match, the rate at which an inning ends in a score, and the rate of leaving a genuinely intended safety. For snooker I need the count of breaks of 50 or more, the century count, potting rate, safety rate, and the win rate in deciding frames. For pool I need the pot rate on the break and the win rate after an opponent's error. In practice, at domestic amateur events, I receive almost nothing.

Tran Quyet Chien, Nguyen Quoc Nguyen and Ma Minh Cam have written their names onto international three-cushion carom rankings; Duong Quoc Hoang is known in pool. Their names exist in international data systems. Their domestic match data barely exists in any retrievable form. That is the paradox I have chased for years: Vietnamese players compete very well, but Vietnam has not kept enough to prove it with numbers.

There is a trap I run into constantly. People package innings played, table visits and training hours as indicators of effort. This is exactly the running-distance problem in football: a player who covers twelve kilometres, most of it useless, still receives a beautiful indicator. Billiards is the same. A cueist who stretches a match to forty innings with many meaningless safeties gets praised for endurance, while the average per inning tells an entirely different story. An effort indicator rewards stamina and hides inefficiency — which is why I never read a billiards statistics sheet through a single column.

Above the player sits the tournament system, where format decides how much luck counts. A nine-ball race to 5 differs enormously from a race to 11 in upset probability. A 40-point carom match differs from a 50-point match in how the closing innings must be managed. Domestic amateur events are mostly short, with small round-robin groups, so a title is sometimes just the outcome of six short matches. I do not dismiss that achievement, but I refuse to call it a conclusion about a cueist. A six-match season is a signal; a conclusion needs more.

The heaviest part sits in tournament integrity. Globally, the most serious governance issue in billiards is betting-related match manipulation, and professional bodies have repeatedly handled it with suspensions. I name no individual here, because I hold no evidence, and empirical discipline does not let me substitute speculation for evidence. My point is structural: a monitoring layer that receives no data will report "no risk", and that state cannot be distinguished from "no monitoring". Silence proves neither innocence nor risk. It is simply the absence of observation.

At industry level, the transmission chain shares the same fate. Clubs develop cueists, cueists create tournaments, tournaments create broadcast content, and only broadcast content can be sold to sponsors. Without data, sponsors cannot price what they are buying. Without pricing, money arrives late and arrives short. At the other end of the chain, talent identification must rely on hearsay, so promising teenagers surface later than they should.

The media narrative follows a different orbit. One amateur title is enough to label someone a prodigy, and I understand why the claim spreads. But the first test is always sample size: how many matches, against opponents of what level, in a long or short format. A nineteen-year-old winning six short matches is a signal worth recording. Calling it a conclusion is both premature and unfair to that cueist.

The counterintuitive part is this. The industry's instinct when data is missing is to buy equipment: tracking cameras, scoring software, table-reading machines. Bolting equipment onto a process that has not yet defined what counts as a statistical event only produces noise faster. I have received twenty-page reports whose input data quality was worse than a handwritten sheet. What is missing is vocabulary, not machinery. While the industry has not agreed which inning counts as an attacking inning, every piece of software is meaningless.

In the empty stadiums of 2026, I heard the ball roll and the note sheet drop onto a seat. When I analysed five hundred European matches played without crowds, the home win rate fell from roughly 45% to roughly 32%. Those data points were not wrong. What disappeared was the context that travels with an indicator. Domestic billiards is in that same condition at a larger scale: missing data, and missing the context needed to read data.

The first step is cheaper than people assume. One discipline, one scoresheet template, one complete tournament. I would rather have one correct column than ten named tournaments without numbers. Before believing a number, I ask where it was born. Just as I watch a player before I pass judgement.
