Think about what the piston is doing. Compressing a static volume of air by a given ratio = 100 psi "compression".
Idle does this about 800x a minute. WOT about 5500. Its still just a static volume by a given ratio. You will get more blow-by when the rings are cold. But you wouldn't run a cold engine WOT anyway.
