Of course, I work mostly off RPE with the RPE for different exercises varying week to week (I program in 5 week blocks). Most of my work is done in the rnage of RPE8-9 although occasionally I will have sets programmed as high as RPE 10 or as low as RPE 6. The lighter stuff tends to err more on the side of RPE 6-7. That being said, I dodn't pick numbers based off RPE, I have a certain weight that I have to hit for the workout and I must do between X and Y reps and I just try to progress my weights at a pace that allows the target RPE to fall in the desired rep range.

for example one of my back workouts this week was structured as follows:

Strict BB Row (closer Grip) 3 sets of 6-8 reps at RPE 8-9 275lbs

Weighted Chin Ups 3 sets of 3-5 reps at RPE 7 105lbs

Weighted Chin Ups 2 sets of 10-12 reps at RPE 6 65lbs

DB Rows 2 sets of 12-15 reps RPE 6 75lbs

In addition to this I did some trap work and rear delt work that is programmed a little more variably.
