gents, again- the idea of starting the callout a little early is to reach the actual v1 speed when you have spoken out the "vee one" phrase. and since its a little slippery procedure e.g lufthansa as well their daughter companies do not call out "vee one" but "go" at the actual v1 speed. spelling go is faster than vee one and the procedure is that when when you start to hear the go the procedure is just to go.
so the guy the thread opener spoke to is spot on- not the v1 is lovered but just the callout is spoken a second earlier , thats all the secret about this whole discussion.
"Weellllll, we don't really lower V1, we just call it early."
