My calculations are with respect to traffic safety and injuries, using only data gathered by the federal DOT. DOT may use ER data, among a number of other sources some of which are listed in that first manual I linked you to, but I haven't drilled that far. I'm using DOT data, concerning traffic incidents. It does not pertain to mountain biking, or anything off-road.
An ER analysis is a different look at a different set of circumstances, for a different purpose. It does not confirm nor contradict me, unless someone sets up a related calculation with enough similarities to compare. Since my math is wrong over and over again, and you present the paper's references as your evidence that DOT/NHSTA data is "drastically understated", if falls upon you to supply a bit more justification other than "I don't have to write a paper". If you want to demonstrate something.
What conclusions are drawn from or by the authors of "Injuries to Pedestrians and Bicyclists: An Analysis Based on Hospital Emergency Department Data" about the probability that any cyclist will suffer any injury during a year, which would be or was mitigated or avoided by using a helmet? If there is such a conclusion that you can deliver to us, your belligerent style would be made worthwhile.
