Billiards and the Data Gap: When the Perfect Shot Has Nothing to Measure

In three frames of a recent regional snooker quarter-final, the leading player stretched his safety run through nine consecutive cue-ball placements. The official statistics credited him with exactly one line: “safety success 100%.” No one recorded that each of those placements pushed his opponent into a different cushion angle, that the pause between shots grew shorter, and that it was this very silence that broke the match open. I have sat long enough in the commentary booth to know that what makes a player is not what the scoreboard records, but precisely what it leaves out.

Twenty-three years of commentary for VTC carried me through nearly the entire golden age of snooker — from finals in which Steve Davis and Stephen Hendry turned every frame into a duel of wits, to the era when Ronnie O’Sullivan redefined the speed of the game. But it was only when I sat down as a data consultant that I recognised a paradox: billiards was born to be measured, yet its data is startlingly thin. Football has xG, PPDA, distance covered. Billiards has… the frame score. And almost nothing else.

The paradox is no small matter. A sport in which every shot can be reduced to probability, in which every position is a geometry problem, is being run on the crudest numbers available. When a tournament publishes its entry list, fans know the names but not the real form. When a player wins, people remember the beautiful break but not the safety sequence that opened the path to it. Billiards’ data is forgetting the very thing that makes billiards.

I tried to rebuild a set of metrics for billiards the way I once did for football, and the gaps kept surfacing. Before believing a number, I ask where it was born. Just as I would watch a player before judging him.

On technique, billiards has a few things that look easy to measure: pot success, century breaks, 147 maximums. But they are all output metrics, not process metrics. We can count how many points a player scored, but not how many chances he created for himself. In snooker, a proactive safety push is worth as much as a difficult pot, yet only the pot gets recorded. We are grading the tip of the iceberg and calling it the whole person.

On players, personal data revolves almost entirely around titles and ranking. We know how many events a player has won, but not how he won — by attack or by defence, in the deciding frame or in the first round. The age-performance curve barely exists in public statistics. In football, I can look at a 33-year-old and say where he stands on the peak of his career. In billiards, I can only guess, because no one writes it down.

On tournaments, format structure is an undervalued variable. An event played in short format — best of 5, best of 7 — creates far more room for upsets than a long-format event. But rankings add points almost linearly, without distinguishing that a title in a short format differs from a title in a marathon. I once compared two players with the same number of titles and found their win rates in long matches differed beyond belief. Format is part of the result, yet data treats it as a backstage matter.

On the power map, billiards still runs on an old order: a group of famous names at the top, a broad middle tier chasing, and a new generation knocking at the door. But without an index of each nation’s pipeline depth, we are looking at a list of names rather than a current. How many young players from a country actually reach the later rounds? Is that ratio rising or falling each season? These are things current data cannot answer.

On rules and governance, billiards is thankfully less scandal-prone than many sports, but that very silence makes risk hard to see. With no public data on unusual matches, dispute rulings, or wildcard mechanisms, fans’ trust must rest on… trust. For a sport as individual as this, where every shot lies in one person’s control, this is a gap that should have been filled sooner rather than later.

On career and psychology, this is where data is thinnest. We know how many points a player scores, but not what he lives on, who he trains with, or how he keeps his rhythm. The shots in deciding frames — the clearest reflection of nerve — are barely recorded as a separate metric. Nerve is remembered by feeling, and so it stays forever outside any table.

On risk, a sport that cannot measure form cannot warn of decline. No one spots a player slipping until he loses several matches in a row. No one sees signs of overload until the cue trembles on the decisive shot. Billiards’ greatest risk is not losing its throne, but losing the ability to see danger before it becomes a result.

On the public, billiards lives on inspiring stories — an unknown player suddenly shining, a champion returning after a string of blank days. But with no underlying data, every story is equally easy to inflate or forget. Attention concentrates on a few names, while most players performing to their true level sink into silence.

On the industry value chain, billiards is a complete ecosystem: from small clubs and cues to tournaments, broadcasting and sponsorship. But the flow between these links is barely measured. Does a rising player draw new players into the clubs? Does a tournament that attracts sponsors push cue prices up? These are things the billiards industry should answer for itself, with its own numbers.

There is a paradox I learned after many years: the more you measure, the more easily you believe you understand everything. Football is the example. When xG became a universal yardstick, people began judging a striker by a number instead of by the eye, sometimes forgetting that a goal comes not from probability but from a moment. Billiards goes the other way — so short of data that fans must trust feeling. The problem is not too few or too many numbers. The problem is that between the two extremes, we forget that data exists to serve the story, not to replace it.

I used to think a sport with complete data would be fairer. Now I am not sure. If billiards had a perfect set of metrics, would Steve Davis be remembered as a master of the slow game, or merely as a player with a high safety rate? Would Stephen Hendry be remembered as the man who changed the pace of a generation, or merely as a player with an outstanding break rate? Metrics record results, not the trace of a human being on the table.

The 2026 World Cup taught me the most important lesson: numbers are only beautiful when they know how to stand on the side of the story. Billiards, so far, still stands on the margins of its own story — not because it has nothing to tell, but because no one has picked up the pen to write it down.

So what will be the signal for the next stretch? For me, it is the first sign of a set of process metrics: not more pots counted, but the beginnings of measurement for the safety placements that opened the path to them. The day billiards builds a data threshold delicate enough to see the submerged part of the iceberg, that day the sport will be better for viewers and fairer to the very people who play it. Until then, I still sit with the numbers when the stands have gone dark — you may call it work, I call it fate.
