Well, there's that too. If I cared about the scores I might have an issue with this scenario:
What if a guy shows up on Friday, but races with only a few other boats, scores 3 bullets, against 3 boats. Then he leaves after three 6ths's on Saturday when there are now 10 in his class, and doesn't race on Sunday? Do you "average" the 3 bullets for his Sunday scores? Is that fair to the guy who posted 3 bullets on Saturday against 10 boats?
Or is racing on Sunday mandatory to get the average of the Friday scores?
Like I said, I really don't care, just wondering if it will p/o the ones who do care.
