Your depth looks good. Your first one (495) was the best.
It sounds like you have some USAPL experience (we are USAPL’ers) On the technical side, setting up the 515, you never lock your knees or stand still enough to get the squat signal. You would have waited for what seemed like an eternity for the squat signal. Also, make sure you get in the habit of locking out your knees and demonstrating control of the weight at completion. Hold it for a one count in your head before you rack.
Also, I can’t tell how wide you grip the bar, but your elbow’s need to come down and get closer to your body. Judging by the videos, they are in a position that when you hit a limit attempt, will have the potential to push you forward. Check it out. If we were training with you, we would try to get you to keep your elbows in the position they are in when you first get under the bar before you start to unrack. IMO, that’s where they need to be throughout the lift.
Are you currently doing alot of band work for your squats? If so, this could contribute significantly to the stabilization on your walkout. My recommendation would be to get off the bands 3-4 weeks out and go to straight weight or chain. This will help you stabilize the weight.
Otherwise, your strength looks good. The way you handle that 515 tells me you should be good for 540-560 come meet day.
Good luck, dude.
