Q for Powerlifters re: high-bar squats

So I’ve started training again after a 5-year break from lifting (work and kids). My numbers are coming up more or less like I would expect after 3 weeks: bench 225x5, deadlift 245x5. On both those lifts I feel like I have a lot left in the tank at this point too, so that’s good.

The number that’s throwing me is my squat, a hard 175x5 today. I could have squeezed another rep but that’s it. I expected my weight to go down because I switched to high-bar squats since it suits me better, I can keep my back flatter throughout the lift. I’m not training to compete but I really didn’t expect to lose this much weight going to that style lift.

My questions:
Has anyone else switched from a powerlifting style squat to the olympic style or vice-versa and, if so, did you see this kind of difference in the weights? I’m taking it slow building the lifts back up so the supporting muscles and technique can come along at the same pace but I don’t want to go this slow. :stuck_out_tongue:
