Please give me some feedback. I appreciate it, thanks in advance.

The Periodisation Method you use is very outdated.

Read Dave Tate’s Periodisation Bible for a deeper understanding of conjugate Periodisation - that will be better for your goals. Feel free to discuss about it here.

I guess I would sort of ditto what fahd posted. Perhaps a little plyo work during each of your phases, a little speed work during each of your phases, etc. So maybe drop the phases all together, but still do some mini-phases (progress in intensity from weeks 1 to 4, then do it over again) with your assistance/supplemental work. Start with some higher reps, over four weeks drop it down to 3-6 per set, whatever. If you wanted to stick to your outline above, at least throw in some plyo/speed work in each phase, along with some more unilateral work in each phase. Single leg squats, etc. I think you would lose some of your baseline strength and burn out your CNS if you did that much plyo work in the end.

That being said, it looks like you really put some thought into this, and I am by no means a S&C/performance coach, just a lowly personal trainer with a vigorous interest in such things.
