Read what I said before. Doesn't matter how many you can do–that's not the end goal. The goal is to do a couple/few fast. If you read some of Charlie's posts your will see some examples of pro sprinters he has used. He mentions that Zhanna Block had by far the highest work capacity and complete the most 100s in a fast time with shorter rests (I forget his exact example–it was something like 6-8x100m with 8mins rest or something), yet she would lose to Marion whenever Marion was 100% because of higher speeds. Since Block would try to lower the rests or add reps rather than extending rests on what she was already doing, she never hit those top speeds needed to further both her max speed AND speed endurance abilities. I know you have some sort of illogical hate for anyone who likes what CF says or his belief or whatever, but read what the man has seen from experience that also happens to be logical.
