Just a quick question, but a friend of mine and I did a compression test on his RX7 recently, and after everything was said and done we got our numbers and put everything back. Afterwards he couldn't remember if he depressed the gas pedal and was wondering to me how much of a difference it would make to his numbers.

My question is what kind of difference can we expect with a fully depressed gas pedal vs. not depressing it when he cranks the car?
