Nice post Wouter, I need to go off and have a think about this one, but here's one for you "Under SCHRS/Texel Gavin Colby is racing himself in a F18 Tiger and a Hobie 16 in a W/L race, if the measurement system was perfect then he should have the same corrected finishing times for both boats, my money would be on the Colby F18 correcting out the winner"
