Expected goals — xG — assigns each shot a probability of being scored, based on how similar historical shots performed. It is the clearest example of what sports analytics does generally: replace
A transition that a substantial proportion find genuinely difficult — financially, psychologically and practically — and which the sports system has historically prepared them for poorly. Why it is
It varies enormously, and the record is mixed enough that "legacy" has become one of the most scrutinised claims in the bidding process. The failures are well documented: purpose-built venues for
Either by pitching a prototype to a publisher, or by self-publishing — and the two routes involve completely different work, risk and reward. The traditional route: Design and prototype, starting
Through a licensed capacity, trained stewarding and detailed planning — a system built largely in response to disasters, where the causes were repeatedly found to be crowd management failures rather
Works on the mental and behavioural side of performance — attention, anxiety, confidence, motivation and recovery — and increasingly on athlete mental health, which is a related but distinct role.
By a qualified measurer using a calibrated bicycle, following a precisely defined method — because a road race distance must be verifiable and cannot be taken from a map or a satellite trace. Why GPS
Through a long pipeline in which most participants do not make it, and the structure of that pipeline explains both its successes and its well-documented harms. How players are identified. Local
Represents an athlete's commercial and contractual interests — and the job is far broader than negotiating transfers, which is the only part the public sees. What the role covers: Contract
Usually some combination of the club, private investment and public money — and the proportion of public money is consistently higher than fans assume, which is why stadium funding is politically
They test completely different things, require differently built and differently trained horses, and are among the few sports where two athletes of different species compete as a partnership — which
Grid first, then fill, then clues — and the constraints tighten at each stage, which is why the grid decides how good the finished puzzle can be before a single word is chosen. The grid. Must be
Both, and the proportion depends entirely on the timeframe — luck dominates a single hand, skill dominates over a large sample, and the crossover point is the whole subject. Why luck dominates in the
Boats race around a course marked by buoys, and the distinctive feature is that competitors police themselves — there is usually no official on the water making decisions, and boats that break a rule
By solving a constraint satisfaction problem — one with so many competing requirements that it is generated by software, and the days when a person did it with pen and paper are long gone in
A planned reduction in training load before competition, allowing accumulated fatigue to dissipate while fitness is retained — and the reason it works is that the two decay at very different rates.
Several distinct disciplines with different demands, different tactics and different equipment — and the word "cycling" covers events that have almost nothing in common beyond the bicycle. Road
Each has its own rules about what counts as a legal attempt, how many attempts you get, and how ties are resolved — and the details decide competitions far more often than raw ability does. The
Breaking the technical definition of the stroke, and the rules are far more specific than spectators realise — which is why disqualifications frequently look invisible from the side of the pool. The
Players are paired each round against someone on the same score, nobody is eliminated, and everyone plays every round — which lets a large field be ranked meaningfully in far fewer rounds than a
The idea that aggregating many very small improvements across every controllable variable produces a meaningful competitive advantage. It became famous through British Cycling, and the honest
Because prize money is generally set by each competition's own revenue and commercial position, not by a central authority applying a single standard — so equality has had to be achieved competition
Through monitoring of betting markets themselves, rather than by watching the sport — because the most reliable signal that a match has been corrupted is money moving in a way the sporting situation
Because tickets for popular events are deliberately underpriced relative to demand, which creates a gap between face value and what people will pay — and any gap that large attracts people to capture
