Is the serve mix in equilibrium?
Game theory says a well-mixed server wins equally often with every direction they use. If one direction wins more, it's underused and points are being left behind. This is the minimax test Walker and Wooders ran on Wimbledon finals, applied to every charted first serve. Win rates include faults. "Optimal" allows for returners reading a habit. No measurable response (−0.05 ± 0.15 points per 100 serves for every 10 points of habitual usage), measured from ATP servers whose mix drifted between matches. Shifts stay within the range servers' habits actually vary, the only range that response was measured over.
Deuce court
| 1st serve | Usage | Points won |
|---|---|---|
| Wide | 58% | 57.5%±9.3 n=47 |
| Body | 15% | 50.7%±12.7 n=12 |
| T | 27% | 40.4%±11.2 n=22 |
Off equilibrium (p = 0.016): serve wide more. Gap 5.7 points per 100 first serves.
Ad court
| 1st serve | Usage | Points won |

| Body | 8% | 60.1%±13.4 n=6 |
| T | 35% | 53.8%±10.9 n=27 |
Consistent with an optimal mix (p = 0.69).
