It's rare that all lifts progress at exactly the same rate. Program each lift individually
I tried searching this and didn't find anything but I might just be bad at searching. Any reason why you can't run out the deadlift and squat at different times on TM? My 5 RM deadlift is still humming along but I think it's time to move the squat to triples. In case it's relevant: Squat intensity day is 335x5 and deadlifts are 380x5. I do my deadlifts on the start of light day as suggested in one of Jordan's 12 ways to skin TM.

Indeed. That's the hardest part about writing a book like PPST3 or any other article/book with a programming template. There is no way to pre-emptively write in all the little nuances and differences that might occur with each individual lift. You have to give the model some level of uniformity across the board or it will read like Sanscrit. But most programs turn into Sanscrit and not Shakespearean Poetry.
I noticed about an hour after making this post that the book has the deadlift and squat running out at a different rate anyway. Oops. Searched the forum. Not the book.
