Default Bought another S2000 and here are the compression numbers

Cylinder # 4: 285
Cylinder # 3: 265
Cylinder # 2: 260
Cylinder # 1: 275

F22C 88k miles - stock motor. Surprisingly, no leaks anywhere.

Between cylinder 2 and 4, there is a 9.62% variance.

Are the compression numbers a bit too ambitious?

This test was performed after driving a few miles.

Never seen numbers that high. Maybe the gauge calibration?

Anyway, what is important is the variance, and there isn't any worrying levels of imbalance here...
