I know it’s hard to read and I’m lucky enough to have got the info from the horses mouth so don’t have to rely on a poor translation but if you think carefully about what Volume 1 shows it basically backs up what Charlie has been saying about how training should progress from year to year. It shows that across all events when you are a developing athlete all types of training lead to improvement but once you are elite then it is improvements in CE (Speed, Speed End and Special End in a sprinting context) that lead to improved performance. It also shows that once you have developed certain levels of strength (SPE) then going for more won’t necessarily lead to better performance if you are a high level athlete - again Charlie’s note on Ben’s 600lb squat.
This on it’s own is valuable information given the fact that it actually has some statistics to back up what people have been saying anecdotally for years. If you want to fully understand Dr B’s ideas you should talk to Scott Saunders of the CACC as he used to train under him and has the ability to explain what he observed.
