I don't think the tucking is that bad, I think it's something that's normal and noticeable on every squatter, but it's harder to see on wide stance squatters.

There's just no way not to tuck the pelvis once you get to a certain depth, although maybe you are starting to tuck too high in the squat and maybe that can be improved. But nobody could squat atg while maintaining a strong arch at the bottom.

During the squat you should try and maintain the arch, but its going to tuck a bit anyway at the bottom, so I wouldn't worry. But maybe if Trevor mentioned it you are tucking too much, and too early and it could be a mobility issue.
