We race every week under SCHRS with Nacra 20's, F18, F16 and A-Cat. There hasn't been much whining at the bar lately. None as I recall, even when the splits were under 5 seconds. The team that sailed best that week usually won. It is very difficult to argue with a formula.
Of course you would since the F18 owes other boats less time under SCHRS. I could find a lot of ways to argue with a formula that tries to cover something so dynamic as boat potential. Have you seen the number of variables that go into the formula? Those guys have put an incredible amount of brain power into it but who says it's any more accurate than our current Portsmouth numbers? How do you prove it? The fact that nobody complains is hardly proof of anything other than the fact people accept handicap racing for what it is.
