Speed endurance the key to *all* 11/12second sprinters?

I have triple periodization graphs but not related to Bolt. I do believe that, when push comes to shove, Bolt is following a S-to-L approach (albeit with plenty of tough tempo sessions, though I think they are still extensive- for him and prob only him due to his max speed) He competes first over 100m and then moves to 200m.

I still don’t understand why everyone thinks Bolt follows a S-L program…
