added to which - is trying to put a handicap rating between a foiler and non-foiler even practical? It's kinda like handicapping a spin boat vs. a non-spin boat on steroids. You can put numbers on it but the capabilities are so wildly different in various conditions (and configurations) that any number is going to have very inconsistent results. Personally, I would give up on the idea that you'll ever have a reliable handicap number to compete foiler vs. non foiler.
