Part of it I think comes down to trial and error to a point like Nord said. I know we shouldn't be trial and erroring with such things as our ligiments but everyone has a certain style and every binding is different.
Having said that, I am supposed to be set at 8.5 on my dins according to the charts(6'3", 180). However, I kept ejecting on places where I shouldn't at 8.5. ie crossing a small crud bump, ski fly's I still stand and keep going type situations. I cranked them up to 10 and didn't have any more pre-release problems until my regional ski meet. I was doing GS and was coming through the middle of a turn at full speed and hit a small small rut and next thing I knew my ski was next to me. I was balanced right so my inside ski took over and I didn't crash. Knowing that, I probably should have tightened them for the race considering the importance of it(regionals) and also cleaned my boots more, nearly spotless but I guess i missed some snow.
My point, as a racer you just need to find what works for you and your equipment.
p.s. I am also in the midwest where bullet-proff is a way of life and the m.o.
p.p.s. I also should say I dind't go straight to 10 from 8.5, I took half point steps to get there to solve it.
