Major improvement in my keeping my reps going without taking a break. Also trying to focus on staying on my mid-foot so I'm not rocking back.
Nobody has directly responded re: whether my lower back is well-set. I consistently feel a small amount of stress that doesn't feel like good stress in my low back, mostly during the first rep or two, and resulting soreness afterword. It isn't very bad and it isn't getting worse, even as the weight goes up. So I continue to focus on a good set, and if nobody sees a problem, I assume I should keep on keeping on.
As for this set, any and all input welcome. Especially if you see anything degrade over the first 4 repeated reps.

To all the coaches and users who have input before, thanks a ton - this feels so much better than when I first posted here!!
