I don't think so. I surmised that Pfaffi's table relates to planing in low wind with a with a wide planing board la Formula and what fin lenght can achieve that goal according to what body weight. His table is found for the developpement of his Formula fins.

I don't think his calculations are valid for a narrow raceboard. I suggest you ask him directly by email:

Cheers !
