My one and only concern here is that people aren't posting their times, because it hurts the team average to do so.
I don't want anyone to ever think that they aren't worthy of being in their team. This is what the change should alleviate. You post, and if the score helps, then it's counted. There's never any question of posting, and the other team members rousing on you for dropping their average.
I don't believe that there are any people whose scores would never be counted... but if they do exist, then isn't this an incentive to put up that bigger sail, bag it out and grit their teeth that little bit harder? Or get that planing exit? Or simply sail all day to get the max distance score (my secret strategy

).
People who have logged on in the last day or so might have noticed the new hyperlinks to the "personal bests" page... without spelling it out explicitly I see this as the way forward... (Shhh!)
