Also I wouldn't say you're going so heavy its dangerous, form looks ok tbh. But that rep speed imo is a bit slow for general training, idk how often you do that - but generally that should be on the infrequent side unless ur just a slow dude who grinds, then maybe its normal for you.
And I wouldn't want to do more than a double with it, I don't think slow reps are that useful (ymmv). I think if your position sucks due to tightness then work on that, but tightness in itself isn't as big a problem - my pauses are done extremely different from comp squat, I just try to push with my legs with just enough core tension, nothing crazy tight. But I can hold positions quite well even with heavy weight - its high bar and less bent over and my leverage's are pretty good for the lift.

Don't do pausies regularly, in fact only done them twice ever at non warmup weights.
Can often grind out quite a lot but don't tend to do so on squats that often because grinding squats is horrendous. Paused reps are always slow for me too, perhaps because I rarely do them, and I don't think I'm ever a huge amount quicker on the ascent even without pauses.
tbh I probably need to think about tightness properly in all of my lifts. I've never really bothered and just lifted. Should start using belt again and finish breaking it in...
I think a part of it is that the bench is much better than my old gym. At gymbox the benches were really hard and slippery which meant that a good arch was very difficult because my shoulders would slip away. I can get a much better, tighter arch here which really helps.
Deadlifts (belted to break it in more) 160 x3,3,2 (then had to take off belt because its ****ing hard to get into position and kinda sore), 2 more in the same set.
