As per @Frank_C s comment I have no business on commenting on the execution of your lift.
FWIW, I recall hearing/reading that Dave Tate will have his powerlifters train to the depth of hip joint parallell to knee which is not competition depth. Only when the competition is close will they then start going deeper. The reason being that going wide and going deep oftentimes leads to banged up hips. As an addition to that, I’d imagine that people that never compete that still want to squat wide might benefit from periodically going to depth to ensure that they can express their strength through that entire ROM.
What I can comment on, or rather share thoughts on, is perhaps this as I have spent some time of my own adjusting my grip- and stance-widths in the past.
Personally, I do not thrive if I change it up wholesale across all my sets. Mentally, it drains me to feel weaker across all the work I do. Therefore, for me, I’ve used the modified widths on my supplemental work, or my warm-up sets, or any variation thereof and left the main work alone. It takes longer to feel out the new “style”, but it also strikes me as less of an “all eggs in one basket”-affair. The obvious exemption to this strategy being when changing because the “old” way is seemingly injurous.
Having the right motivation also helps. I find that it is best if there is a reason to justify changing the width, such as banged up joints (for me this happened on squats) or not feeling a prime mover participate (triceps on bench) rather than just “it’s odd that I do it like this, in theory it should probably be this”.
It’s obviously really tough to tease apart if the stance is objectively weaker, or if it’s because you haven’t had as much practice with it. I view it as an endogeneity problem. Because the variables in this context travel together, but might not be causally related, i.e. your stance has an impact on your strength potential, and the amount of practice you’ve had in that stance affects how much of that strength potential you can express, and the level of practice you’ve had informs how you feel when you execute the movement.
If you were to change the width for all your work Swede Burns suggests staying with the same training max but work at around 70%
Just some thoughts, you are strong either way, just if you want to play with changing things.
