lol.. no... Pipemax uses actual valve lift, duration at .050, degreed centerline, and cam Lobe Seperation Angle to extrapolate e symmetrical lobe. Then it applies that curve to the crankshaft degrees and gets a number. So it's a figure based off a generalization, like all these programs. But, it's a fun thing to play with sometimes. I use the KB site for quickie calculations too. That uses a generalization for the "plus 15°" so again, it's a tool not bible. The inetersting thing is if the lobes spec'd were assymetric, and I'd bet they were... then it should have had MORE cylinder pressure than the 9.5... And probably more oil contamination of the chamber too.
