It's very hard to get accurate information on a lot of methods, how would you go about getting the data?
Many methods are dependent on so many extreme variables, it seems almost silly to group them. I tend to take it all with a grain of salt these days
Jumping will depend on height, drag, impact surface, etc.
Drug poisoning will depend on quantity, purity, time until discovery, etc.
