Knee travel on squat stance slightly outside shoulder width

I have a pretty wide squat stance outside of shoulder width with minimal knee travel.

I feel strongest and feel I can get better depth with this setup. I’ve always learned through various videos/form checks that the knee must go about 1 inch past the toes. Is this a hard and fast rule or depends on anthropometry and setup? Should I work towards narrowing my stance slightly or just keep it the same.

Here is a set of 4 @ 7-7.5. Sorry about not getting the whole body. I’ll try to get a side angle shot next training session as well.

They look high and you have some knee cave. I’d bring the stance in and focus on pushing your knees out. Should be easier to hit depth as well.
