Low compression 440 dyno test

Just curious. Have you put a compression tester on it to see cylinder pressure? Not that it matters, because with good dyno numbers and I'm sure it puts a smile on your face, that's all that matters. I'm just curious if those Whiplash cams do "optimize" cylinder pressure like they claim. ....but again, it's makin the power, so what's the difference?
I planned to, because I'm curious also. Just never got around to it.
