Good job sticking to the plan thus far bro. If you're starting to feel run down at all, at any point, then drop the extra accessory work until you recover. The heavy presses and pulls will more than take care of those pythons.
Also, on the deloading, make sure you're doing 3 sets of 3 reps per exercise, not 3 sets of 5 reps. The deloading should keep you lifting as heavy as you did while loading, yet become easier with only 9 total reps vs. 25 reps.
Just keep at it and as long as you continue climbing, there won't be no reason to change a thing until you need to! If you ever get bored with this, since you've been at it for so long, feel free to tweek an exercise for a month with a new rep range albeit 5 sets of 1 rep, 3 sets of 8-10, ect for every Monday's squat (for example). Just to keep you interested in what you're doing.
