Can someone tell me if I'm understanding this correctly?
For each muscle group, there are three different phase groups (P, RR, S). Let's assume there are three possible exercises under CHEST

OWER. Dumbell bench, incline press, weighted dips. This means some exercises will not be repeated for 9 weeks?
Ex: You will only do CHEST

OWER once every three weeks. On top of that, you are rotating betweek each of the three exercises. So after you would do dumbell bench, you won't be doing that one again for 9 weeks?
The reason being the next time you do CHEST

OWER will be in three weeks, and you'll do incline press. In another three weeks when you do CHEST

OWER you'll do weighted dips. Another three weeks later you'll be back to dumbell bench.
Meaning...
Week 1: Chest Power Exercise A
Week 4: Chest Power Exercise B
Week 7: Chest Power Exercise C
Week 10: Back to Chest Power Exercise A
Is that correct?
