Super work Scot

I saw it posted last night and have read through it a couple times and played with calcs. It does seem to be more representative of prices seen the past year or so.
A question: For the baseline P350 where you had values of PSA/SGC 3 = $40, 4 = $60, 5 = $100, what were the correlation coefficients (R-Squared)?
Best Regards
