Just been re-reading this after last night and I need to pick you up on one comment that is a fair way up the thread Wouter.

I know you are just having fun and all but are you really aware that under both Texel and ISAF :

1-up F16 is rated 1% faster then both A-cat's and F18's.
2-up F16 is rating 1 % slower the both A-cat's and F18's


Not quite true.

F16 one up rates at 0.98 currently
F16 two up rates at 1.02 currently
F18 Rates at 1.01 currently
A cat rates what the measurement cert. says it rates, as they are development classes; we currently think, under the current rules, that the fastest A classes (Flyer etc) rate at about 0.97, we are trying to get one measured.

F16 - GBR 553 - SOLD
