Wouter,
Stay away from our rating system. It is just fine the way it is and it is based on fact.., not some ficticious figure that you happen to think is correct.
When I race my 4.9 in CABB races the number works out just about right -- usually between 3rd and 1st against some of the best sailors in the USA. So why would you want to butt in and have it so I finish 10th or 12th?
