Hi Mark,
I didn't know that option is available in Sailwave. Our club uses it now and it is a significant improvement over previous methods for scoring the Portsmouth fleet. It seems to make sense and the fact that all boats experienced roughly the same winds would seem more fair. The N20 would have more opportunity to make mistakes (more mark roundings, tacks and gybes) while the H16 gets each mistake multiplied by the distance factor (3/2 in the example). It all works out in the end, I guess.
