In April - on Tuesday it is recommended that the athlete runs 5x 150 at 95% intensity and in May 3 x 150 at 100% intensity. Not only will these sessions take an inordinately long time to complete -that is if they are to include the recovery periods necessary to repeat the runs at the intensity required BUT and this is a critical BUT - the demands on the CENTRAL NERVOUS SYSTEM will be such that the athlete will be unable to undertake a quality vault session the following day -as recommended in this program.
Have not been on this in a long time I have made some changes on the recommended days since then but have not had time to post them. But you are absolutely right the CNS takes 48-72 hours to recover. What I think I failed to emphasize is that if you do not feel 100% on sprint days don't do them do something else. However I generally feel recovered within about 24 hours if I don't feel 100% when I vault I just do drills and I would suggest other people do the same. But I definitely should have stressed this more, along with the lighter load every fourth week and rest days. Since adaption does not happen during the workouts but during the recovery phase.
