These are high, you should be able to achieve depth without flexing your spine, just keep your erectors tight from the start and do not let up.
Stop pausing, bounce out of the hole and drive your ass up, lead with your hips and not your chest.
I've got a bulging disc (L5-S1) and I'm starting from zero and trying to squat with a perfect form.
Weight on the bar is 43 KG.
Depth is a big problem mainly because in the past I would squat deeper by allowing lumbar flexion, which hurts a lot right now.

I tried squatting again with the same weight.

To my suprise I had no back pain with this form vs the form in the previous video.
My backpain decreased even a little bit after this set.
I do have some major butt wink.
