Just wondering if anyone has ever collated the injuries/fatalities from the varying disciplines (CRW, Skysurfing, Freefly etc) to determine which has the highest probability of something going wrong. I appreciate you could'nt take the results to literally due to the numbers of participants (i.e there are more Formation Skydivers than CRW flyers and therefore statistically the incident level for the former must be greater). There are also other factors to consider, like experience level, freak weather conditions etc. I know the insurance industry had a formula for determining risk factors in 'dangerous sports' which was not based on the number of participants (both horse riding and scuba diving came out worse than skydiving.) I'm only curious because most people see CRW dogs as slightly mad, because of the risks of wraps and entanglements, yet the actual injury level in this group seems (to me) very small. Views?
