Hello. After maxing out on Starting Strength’s linear progression, I started Wendler’s 531 today! Today was squat day.
Below is my video of my last set at 85% for 5+ reps. My training max is 198 lbs., and if I am doing the calculations correctly, my last set was to be done at 150 lbs. (which I did). For background, I’m 49 yo, around 5’7" (maybe 5’8" if I stand ramrod straight), and weigh 162ish.
Questions:

Do the reps look deep enough? Some might be slightly high, but maybe I am being too critical.

I think my bent wrists are getting a little better, but still not perfect.

I did 20 reps on the last set (let’s assume they’re all good ones; see #1 above). Is that too many and/or am I starting at too light a weight? My one rep squat max is 220, so I hope I doing the calculations correctly.

In terms of assistance exercises, I did the following. Is this too much?? If so, what do you suggest I delete or swap out from the below? Thanks!

b. Front squat: 95 x 10 x 5

d. OH dumb bell press: 35 x 10 x 3
e. Lateral size raises (dumb bells): 20 x 10 x 3
f. Cable pulls at various height angles: 33, 37, 40 lbs x 10
g. Push ups: 20 and 20
