I think you missed the point here, Mike. The OP asked if his readings were "within specification" and then all that nonsense pile of wrong simplistic figuring to determine a cranking pressure began.

I totally agree cylinder balance (your 'comparing') is a more important factor than a specific numerical goal, but that's not what was asked!

I was simply pointing out in an engineering way the folly of using some simple arithmetic to circumvent finding an actual manufacturer's spec. The posted dismissive replies were not atypical on this forum.
