Thanks Big Mike for the douche suggestion. I will look up in the sim for regulations on wearing force measuring equipment. I am sure it is right under the paragraph about wearing go pros. Logically, skydiving is so cheap that I have money in my pocket to burn on force measuring equipment.
Yes I am recovering from a broken clavicle. It has been long enough since the injury that I am doing push and pull ups just fine. From what I have read on the internet, it only takes 10 pounds of pressure to break a clavicle. If I were to guess with out using force measuring equipment, there is more than 10 pounds of force on the majority of openings I have packed.
In the three years in the sport, I have not heard of a clavicle break due to opening. Thus, I was wondering if the clavicle actually takes that much impact on opening.
