Rule of 10 Training

Hi all,
I’m still following 531, I am looking through the program options in beyond 531 and I found the “rule of 10 training” and it sounds great. On the percentage of each lift you get 10 reps in anyway possible for example on the 95% set you go sets like, 3,2,2,1,1,1. I am just wondering if anyone uses this, it seems like a good mix of the advanced 531 and regular 531. I was thinking I would do a PR set and make up the difference after to get to 10 reps. What do you guys think of this? Any thoughts are welcome!
