questions about BFS

[Deputy]

Since the BFS looks a lot like an undulated periodization system, what percentages of your 1rm do you use for each set/rep scheme? I was thinking of using the 5rm style in the Bill Starr 5x5 for the 5x5 here but what about the 3x3, 5-3-1- and 6-4-2?

any input would be greatly appreciated
