Vietnamese Billiards and the Data Void: When the Ball Moves Faster Than the Numbers

Football has its own rhythm, and data has its own. It took me years to make them stand in the same sentence. Billiards is different. In billiards, I am still searching for the rhythm of data while the ball rolled past long ago.

At the national billiards championship final held in Binh Duong late last year, I sat in the fourth row from the front, holding a dog-eared notebook. The match entered its third hour. The leading player ran the rack to 47 points, then stopped at a difficult safety. The arena held its breath. Above my head, the electronic board showed only two lines: player name and score. No break-success rate, no count of times opponents were left in their chair, no average per visit to the table. Just two bare numbers.

I turned to the man beside me, a long-serving coach of the provincial billiards team, and asked quietly: "Do you know this player's break-success rate this season?" He shook his head. "Nobody tracks that. We watch with our eyes." That was the moment I realised: in a sport measured in millimetres, we are measuring by instinct.

Context

I have worked as a data consultant for a football club in Binh Duong since 2026. My daily job is turning dry numbers into tactical decisions. In parallel, I have followed billiards — especially snooker — for more than two decades, and once commentated for VTC across many seasons, from the era when Steve Davis and Stephen Hendry dominated the table. Those two worlds, football and billiards, sit side by side in my head every day. And the gap between them, when it comes to data, is unbelievably wide.

In football, a club-level match can generate thousands of data points: passes, xG, PPDA, distance covered, sprint counts. V.League clubs can now hire match-tracking services and analyse opponents down to every set piece. In billiards, even a national tournament usually has only the score. That asymmetry is not a small matter.

In 2026, when I began analysing 240 V.League matches for Binh Duong, I found the team held only 42 percent possession but created 18 goal-scoring chances from counterattacks. From that figure, I proposed a formation change, and the team kept nine consecutive clean sheets, climbing from 10th to 4th. Vietnamese billiards today sits in a similar position: it has enough raw material to build something, but nobody has sat down to count.

Analysis

To analyse a player, the first step is identifying which discipline he plays. That sounds simple, but it is the opening problem. "Break" in snooker, in American 9-ball, and in Chinese 8-ball are three entirely different concepts. A one-visit clearance in 9-ball is nothing like a scoring run in snooker. One term, three meanings, three frames of reference. Without identifying the discipline, every number is meaningless.

In snooker, players are measured by century breaks — 100 points or more in a single visit — and by maximum 147s. Those are indicators comparable across time, from the days of Steve Davis and Stephen Hendry to now. But in Vietnam, I have never seen a complete century-break table for a domestic season. Amateur events, open tournaments, club-organised contests — they all happen, they all crown champions, but the statistical trail almost evaporates the moment the trophy is handed over.

Imagine that happening in football. A V.League season ends, and nobody knows how many goals the champion scored, or which goalkeeper kept the most clean sheets. It sounds absurd. But that is exactly the state of most Vietnamese billiards systems. We have champions, but no statistical history of the champion.

The shortfall has direct consequences. Without data, form cannot be assessed over time. A young player cannot be compared with the previous generation by any objective yardstick. A declining player cannot be detected early, because there is no baseline to compare against. In football, I can tell a coach: "Our PPDA is 8.7, too low to control the game." In billiards, I have no equivalent basis for such a statement.

Rankings are another example. In professional snooker, the ranking system is based on prize money accumulated over a two-year cycle, allowing a player's progress to be tracked step by step. In Vietnamese billiards, ranking usually rests on the most recent tournament result, lacking continuity and rarely published transparently. This makes seeding, bracket placement, and even selecting representatives for international events depend more on relationships and intuition than on data.

Tournament structure sits in the same void. A billiards event can be knockout, race-to-whatever-frames, race-to-whatever-points — these numbers determine how surprising the tournament will be. The shorter the format, the higher the chance a weaker player wins. That is basic probability. But to analyse it, I need exact figures for each event: total prize fund, entries, qualifying system. In Vietnam, this information usually appears only on advertising posters and is never archived into a searchable database.

The competitive landscape is the same. In snooker, the tiers are clear: title contenders in the Top 16, the mid-table backbone at 32-64, the relegation zone, and the new generation from qualifying. In Vietnamese billiards, these groups exist in reality — everyone knows who belongs where — but they have never been mapped into a statistical power chart. Without a map, there is no way to measure movement: how fast the young class is rising, how long the veterans can hold on.

Once I stayed behind after a tournament and tried to reconstruct every match from the final day of play. In six hours, I pieced together less than half. Partly because the organisers kept no records, partly because referees wrote by hand on paper that later went missing, partly because results were announced over a loudspeaker and then dissolved. Six hours for half a day of play. In football, I download a full season of data in minutes.

Rules and refereeing sit in the gap too. Billiards is a sport with complex rules, frequent disputes, and refereeing decisions that can swing a match. But because there is no recording system, disputes exist only in spectators' memory and then fade. With no archived precedents, there is also no basis for improving officiating.

Here, I must say one thing. The data shortage in Vietnamese billiards is not caused by lack of money, but by lack of record-keeping habit. In my early years working in Binh Duong, the club had no expensive software. No automated tracking camera system. Only a few people who believed that every number would eventually find its way. We wrote by hand, copied, cross-checked. Vietnamese football rose from notebooks like that. Billiards can do exactly the same, if someone is willing to sit down.

Before I trust a number, I ask where it came from. Just as I watch a player before judging him. That question applies to a whole system. When a billiards tournament announces its champion, I want to know how the road to that title was recorded. If the answer is "nobody recorded it," then that victory, however brilliant, cannot become a lesson for the next generation.

Back to the personal story. What does a professional player live on? In developed countries, income comes from prize money, sponsorship, exhibition contracts. In Vietnam, most players have other main jobs, and billiards is a passion or a side income. But we have no figures to say precisely. What percentage of players live entirely on billiards? Nobody knows. How many retire before 30 because they cannot make a living? Nobody knows. Those are questions a decent data system must be able to answer.

The media story also reflects the gap. Vietnamese billiards usually appears in two kinds of news: a player winning abroad, or a scandal. Between those two poles, there is no steady flow of information. No stories about training, about daily improvement, about quiet defeats. Because telling such stories requires continuous tracking data. And continuous tracking data is something nobody does.

Deeper still, the entire billiards industry chain — from table and cue manufacturers to clubs, tournaments, and media — operates without connected data. A cue manufacturer wanting to know who uses its product, at which event, with what results, has no source to consult. A sponsor wanting to measure exposure can only rely on rough estimation. When data does not flow, value does not flow with it.

Contrarian angle

Hold on. The first reflex when facing a data void is to fill it with everything. That reflex is wrong.

I remember the days when European football exploded with metrics. Distance covered and sprint counts were packaged as an "effort index." A player running 12 kilometres was praised, while an opponent running 10 kilometres but more effectively was undervalued. But ineffective running also produces pretty numbers. A midfielder drifting without impact can still show an impressive distance. That metric does not measure value, only movement.

Billiards will face the same trap. Once tracking begins, people will count what is easy to count. Successful shots. Times opponents were left in their chair. Centuries. But not everything easy to count is worth counting. A safety shot that looks meaningless, scoring nothing, can be the move that decides the match, because it forces the opponent into trouble that costs them three visits later. That shot will not appear in any scoreboard if we count the wrong thing.

Data is not the destination. Data is the means to retell what the naked eye misses. World Cup 2026 taught me the most important lesson: statistics are only beautiful when they stand on the side of the story. Croatia that year was not the team with the highest xG, but it was the team that ran the most, averaging 112 kilometres per match. If I reported only that figure, I would have missed an entire nation running to compensate for a deprived youth. Luka Modric made 12 key passes per match at 87 percent accuracy — but that number only means something beside the journey of a war refugee boy who became a playmaker.

Vietnamese billiards, as it begins building data, must learn that lesson well. Do not count to fill a table. Count what can retell a human being.

Takeaway

So what is the signal for the next round?

Vietnamese billiards stands before a rare opportunity: to build a data system from scratch, unburdened by old habits. No advanced software is needed. Just one person, one notebook, and the belief that today's ball path will help tomorrow's player.

I am the one who stays with the spreadsheet after the arena lights go out — you may call it work, I call it fate. In the empty stadium of 2026, I heard clearly the roll of the ball and the sound of my note sheet falling onto the stands. Now, with billiards halls full again, I still hear it. It reminds me that every number recorded today is a ball placed correctly for the break ten years from now.
