In reply to:
...a 100 jump life expectancy...for BASE jumping.
Are there any figures available that suggest this ? or is it as i expect a randomly generated statistic ?
It's really only possible to generate reliable statistics for two sites--the legal span in the States and the organized big wall in Southern Norway. At those sites, there are reasonably reliable statistics about number of jumps made, and number of injuries and fatalities.
Based on those statistics, it's quite a bit safer to jump that span than it is to jump the cliff, especially if you are a beginner.
For BASE as a whole, it's quite a bit murkier. Just using anecdotal (i.e. how many jumpers have I known, and how many of them have gone in), I'd say that if you are a "jump until I die" kind of BASE jumper, you have about a 1 in 20 (5%) chance of dying on a jump at some point in your future. If you uses a wider "how many do I think there have been", and look at the fatalities page, I'd still put the number around 5%.
But, since every jump is different, and jumpers risk tolerance vary widely, I'd say that it's pretty much impossible to draw general inferences about a generic BASE jump.
The only real value in the statistics is to see what the causes of accidents are, and try to address them--or to use the statistics to dissuade over-eager students.
