This further illustrates my point. This is the club to which I belong and compete every Tuesday night. There are typically 4 F16s and a half-dozen or so Nacra 20s and 3-4 Acats every week. With rare exception, the F16 take the top 3 spots. We have some great competition among the F16s, as do the N20s and As among themselves, but Series trophies seem to be attainable only by F16s. Our scorer has run the numbers using the F18 PN for a few of the races and it shows that there were very little differences in the results—and I'm sure that results would change for some races.
