Motor Unit Recruitment in Resistance Exercises

This thread has me re-thinking my powerlifting training program/schedule. I have always cared the most about squat, so I squat hard and heavy on Monday…when I am the freshest. I train legs twice a week, but I can’t go heavy twice. So I squat heavy Monday, and do speed deadlifts on Thursday…8x3 w/ roughly 50%. In the past I have noticed significant and drastic benefits following squat workouts where I focused on speed with lighter than usual weights. Watching Pat Mendes squat 800 ATG with no belt, spotter, or safety catches made me believe that squatting fast is the best way. If squatting fast is so effective, and deadlifts train the highest level of MU recruitment, it would only make sense for me to reverse my schedule, training deadlifts hard and heavy on Monday…a sort of Max Effort Day, and a speed/dynamic squat day on thursday. Thoughts?
