Cosmo, I'm referring to after V1 and before Vr (and even after Vr as well, though obviously still over the runway with some useful length remaining). While the phrase has a hint of Boeing covering it's *** to it, it does make it clear that not all circumstances can be accounted for in the book.
safetypee... Personally I believe that you should actually have a quicker reaction with the CA taking over from the FO as he should have been the first to notice the condition necessitating an abort and should already have his hands guarding the throttles and feet guarding the rudders. Where the CA is flying you have to account for some delay in response as he may not be aware of exactly what is going on until some time (even a second) is taken for evaluation.
