IF you can sprint the day after donig squats and deads, you didn't life heavy/intense enough. If you can squat the day after you sprint, you didn't sprint hard enough. Just because you can do it doesn't mean it's optimal. You need days off to recover, grow bigger/stronger/faster.
I don't see how 2 intense strength sessions and one sprint can only get you to 80%?
I've head tremendous success with the following:
M - squat, bench, deads, standing overhead press
W - hill sprints or ladder sprints... 100 meter sprint, 100 meter walk, 200, 300, 400, 300, 200, 100
F - Power clean and press, weighted dips, weighted pullups
Sa - Yoga
Rest of the days just stay active.
