Yeah that's why I said "if you can do full squats safely", because it pretty much depends on structure. By the way, do you feel like you improved on your "bounce (rebound)" at a half squat depth, or is a bounce in there at all?
Why do you think a rebounds is easier at full vs. at half? (meaning - to what do you attribute the existance of rebound anyway)?
Rebound is definitely easier with full squat. Rebound has 3 parts (that I'm aware of)
1. muscle stretch reflex
2. hamstrings/calves contact (and possibly stomach on upper thighs)
3. bar momentum
So you basically say that since that the glute stretch at the bottom, and it's SSC effect (reactive effect) on the power induced for that particular squat is better than the quad stretch and it's SSC effect that you receive when you do say parallel squats or half squats?
more muscle stretch with full squat
no physical bounce from tissues approximating with half squat
and easier to harness some bounce from the bar's recoil (not sure if recoil is the correct word, but you get my point)
