Brian,
I see improvements n what you were working on. Keep it up.
Next things:

I want to to begin adding the following:
When you unrack the weight, stop and let the weight settle into your lats. I call this Shorten It.
It means shorten your stroke.
Unrack, shorten, pause between each rep and shorten again before you start. Hold the last rep for 2/1000 count before returning it tot he hooks.
