Yeah. I wasn't so much worring about form as much as using the box as a protective measure. It is very hard for people to gauge their depth, especially when dealing with heavy weights. Hell, a lot of the times you think your are below parallel when your actually above it. Having dealt with a similar hip injury before and knowing these things can be very ROM specific I know that it is very easy to decide on a good pain free working depth but then inadvertantly go too low and re-injur yourself. But of course, the emphasis should also be on returing to the pre-injury range of motion. But Phil is well aware of that. In the meanwhile he can hopefully soon be squatting again
