Now that I have finished watching it, I will make a real reply.
I wont lie, I have had enough bad jumps to cause some injuries, give me some downtime, and scare the living breath out of me. I also did free fall jumps, which I liked better because of the control, but others didnt because you actually had to worry. By the time I left I didn't even have to think about either, they were as natural as breathing. After a while, it becomes so natural that you can see when the soldiers under you are doing it wrong, but actually have to think about exactly what was wrong.
