You also have to understand that changing a ME movement can be a very small change. Changing reps (5 RM vs 3 RM though I don’t think Louie recommends above a 3RM), grip/stance width, amount of band/chain vs plate weight, bars, etc. If you haven’t read Louie’s Book of Methods, I’d recommend it. He does talk a bit about deloading, but it’s like every 6th week or so if I remember right.
All of that said- you’re going to stall eventually. Go ahead and embrace it. Then start tweaking things. Guys got enormously strong training in completely different ways. If you look at Ed Coan’s periodization scheme, it’s completely different than a conjugate layout, but he still managed to become the GOAT.
Honestly, if you’re seeing progress, keep going until you stall in the same general direction. In my humble (but accurate ) opinion, you’re not going to learn what really works for you until you hit a plateau. When you plateau, then it’s time to pull some levers and change up a bit. Right now, if you’re truly making good progress, you’re most likely not going to speed up your progress by changing templates. As long as you’re training with sound principles and getting in enough rest, keep going. Now if you have a lift that’s starting to lag behind (as your squats may be if you haven’t back squatted as an ME movement in months) , that’s the time to start tweaking and playing.
