Here's a spread sheet with a few combos. For the 66m stoke I tried the measured deck (.85mm) and a 1mm deck (probably stock).
I did the same for a 70.4mm stroke.
I programmed the spread sheet and worked up the CC method from scratch so there is plenty of opportunity for mistakes. If you can review my figures (maybe using your own compression calcs) that would be helpful.
thanks,
Chris
