62 here.
I ran 531 for 7 years before my hip replacement in June.
I found 5 progression with the % of weeks 351 to work best. Rarely deloaded, and lifted every other day.
Main lift , then FSL 3x5 or something similar for 3x10 and then 25-50 reps of accessory type movements.
I almost never did AMRAP, sometimes I would max at 9 or 6 reps ( makes the math easy for new TM). Sometimes just a hard triple. AMRAP never felt as good after. I would work up, after a few cycles just reset the TM and work up again. Maybe change the supplemental movement.
