Tennis Match Probability Calculator
Builds the full Markov chain of tennis from one number per player — the probability of winning a point on serve — and computes hold probability, tiebreak, set and match odds for best-of-3 or best-of-5. Shows how tiny point edges snowball: 52% of serve points against 50% is already a solid favorite.

Notes
- Independent-points mode assumes every point on a player’s serve is won with the same probability — no pressure points, fatigue or momentum.
- Momentum mode lets each won point raise the winner’s next-point chance (the boost fades quickly). Streaks make upsets likelier, so the favorite’s match probability drops toward 50% as strength grows.
- ATP tour average is roughly 64% of points won on serve; WTA roughly 57%.
- Educational estimate for sport and training purposes, not professional coaching or medical advice.
