So how does DUP and RPE work?

[Tom Narvaez]

Your failure sounds less like an issue of overall recovery and more like an issue with your work capacity. Failing the 4th set after the second set was @7 means you're fatiguing too quickly from the work.

You need to improve your work capacity and you're going to need to do that by starting with lower RPEs and not resting so damn much between every set.

Some cardio would help accelerate the pace. One or two Jordanesque HIIT sessions per week will work well.

You didn't overreach from that volume in a single week.
