This is how I would run it, give or take.

By this time your lower back and abs should be stronger (although you may not feel this due to fatigue). Your technique should also be better, so we can start re-introducing some supplemental exercises as well as taking some measures to make you strain safely

By this time you’ll be carrying a fair bit of fatigue so a lot of this may feel slow and heavy, but I would be surprised if the reps don’t move very well anyway. If you wanted, although I advise against it, this would be the time you could take a few weeks to prepare for a couple of singles in the 85-90% range. What I would suggest instead, though, is essentially keeping much the same structure but each wave have a week between 55-65% (20-30 total reps), a week between 70-80% (15-25 total reps) and a week between 82.5-87.5% (10-15 total reps) and keep that moving forward. Your total reps would be set per week within the range while also bearing in mind what your other lower body day involves.
