Alright. I've been having some form issues on my squat and depth is the main culprit, shoes coming early May. Other form issues too but this pertains to the squat.

In the book on page 10 I believe, figure 2-1, there is a picture of a guy squatting. The caption for the photo says "Depth landmarks for the full squat. The top of the patella (A) and the hip joint, as identified by the apex in the crease of the shorts (B). The B side of the plane formed by these two points must drop below parallel with the ground."

What is the apex in hte crease of the shorts? Is it the corner of the hip angle or what? Or should you look at the middle of the side-of-the-hip to judge depth?

I know this is a very dumb question but I don't understand. When I squat I feel like I'm going down enough but I'm always border line high. I'm getting my WL shoes and hopefully that will help.
