Does anybody have any statistics on injuries at Bridge Day?

I'm looking for stuff like:
Equipment- Container,Canopy(7 or 9 cell),D-bag/sleeve/freepack?
Training- Did they have any BASE specific training?
Skydives- Number of skydives, any accuracy training?

It would be interesting to find out if any of these factors are a large cause of bridge day related injuries.

I'm new to the baseboard, so please excuse me if this topic has been covered before.

Thanks
