Powell and Gatlin's Training Methods

so one of these M,W,F speed work-outs progress into 3x (3x90m) then progress 3x (2x90m) then later 3x200m around 20.0X area(for that level)?

Or did that 90m progression turn into 3 or 4 high intensity pure speed 90m runs (ie. accel 60 –> maintain 40 for elite level) with full recovery, like the split run 60m progression into 60m pure speed acceleration?
