I used to live in an area where there were a LOT of freefall parachutists. At the local airport, it wasn't uncommon to see quite a few world recognized jumpers. I have freefall jumped. as well as military jumped, but prefer the relaxation of diving. It is my understanding, that statistically, most certified parachutists are injured between 700 and 1000 jumps. I have met many, personally, that fall into that catagory. Is there a 'danger window' for number of dives? I have pondered a lot about this, and diving is so diverse, it seems hard to catagorize 'number of dives' because of diversity (most skydives are 1. leave aircraft 2. fall 3. open chute 4. land). So for the long term divers, in a single location, is there a number of dives that open present a cautionary period?
