i might be way off on this but has it not been only the last 3 years or so that the F16s have reallly started showing up on the scene here in the US. I know some people were doing the T 4.9 before that but it is not a fully optimized f16 and lot of time i think they did not really run spins with them. And I bet most of those numbers that were turned in went under the tiapan heading not the f16. And since the 2007 numbers have been unpublished this year do to changing of the gaurd I would think that either next years number or the 09 ones are gonna drop. I think Matt M said there were about 45 blades out there. Well 10 of them just got into service with the alter cup and bet the majority have been only sailing for about 1 year (i think Tom and Terry have some of the earlier blades and are only 3-4 years old). I think that the number will soon find itself and we just need to play by what ever the rules are. If it is portsmouth, then the offical numbers must be used and reported to let the system work. But when we are in our own fleet F 16 rules of straight up racing is the way to go. The f16 idea might be 6 years old but it is still rather new on the course in its present setup.
