What I'm trying show is the gain ain't linear in this one aspect, kind of like cr going from 7:1 to 8:1 gives a higher hp % increase than 15:1 to 16:1.
7:1 to 8:1 is a 12.5% increase in compression vs 6.25% increase from 15:1 to 16:1 you would have to go from 15:1 to a little over 17:1 for the same 12.5% increase. I think. lol
