Tennis stats
Objective averages and our prognosis accuracy per competition. The percentages are PROGNOSIS ACCURACY, not profitability or betting value.
The % is the model's prognosis accuracy, not a return. The history is short (since late June) and grows over time, so leagues with few matches don't yet show a percentage.

Frequently asked questions
What is surface Elo?
A rating computed separately for clay, hard, grass and carpet: a player can be much stronger on one surface than another.
What do aces and double faults measure?
Aces are winning serves (serve power); double faults are two serve misses in a row (consistency). Both help estimate games and sets.
How does BetsTalent calculate probabilities?
With an in-house model: opponent-adjusted Elo and, in football, Poisson/Dixon-Coles with per-team attack and defence. In tennis, Elo by surface. No raw averages.
