Wow definitely. Thank you for that critique. For some reason I assume it was magically fixed going from flat shoes to Adidas powers, it might actually highlight it. Now raising the heels with the higher sole I understand why I had this weird new Feeling of going forward on some reps. I didn't get it.
Only other video I have on my phone is a front squat, heels don't move, and it's as high as 95% of my back squat. Guess one is done much better than the other... This explains that
Edit : the more I read it, the more I feel like I would benefit from the 915, hammering those weak points. Today I saw that my deadlift isn't great from the floor and I should work on it. Same with bench off the chest etc. will probably do 2 more weeks of 20-minutes, and do the switch
