Holly, I've replied to your post on VE. You don't actually need to know the P2S distance if you can easily adjust at the base, just a two point protractor.
Simply adjust the board with your protractor to set up the cartridge, like the SME. Just mount the cartridge square anywhere in the headshell and then adjust at the base until the nulls are correct.
If you want more tech info as to why this is the case, see point 2 in
