Shot Pocket Question

I am seeking clarification on the location of the "shot pocket" - is it slightly above the waist with upper arm and forearm making the hallowed 90 degree angle OR is it between the upper chest and the top of the nose?
I have always preferred the waist area as this is the triple threat position and taught a shooting motion that moves through the upper chest area on the way to a release point above the shooting side eye forward of the head.
It seems that women want to use the upper chest to top of nose set position and crush the 90 degree angle with their arms which results in a "push" and big hop forward to the rim with their feet.
Anyways, thanks for all you do, it's greatly appreciated.

The main thing is it needs be comfortable and done the same every time. If you look at the best WNBA and NBA and you'll see 10 different shot pockets.
