With a thread this long I looked at the first page and the last.
There really is no point in debating this apart from certain acedemic aspects to the process which can be interesting since it throws up a couple of curved balls.
There is no data in the FM for braking distances beyond V1. And for good reason. If you decided to flip that particular coin then you become your own test pilot and I'm not too sure the rest of the crew will thank you for it. Even if the decision to remain on terra firma after V1 is taken and gotten away with due to extreme circumstances the post flight euphoria will diminish when the investigation reveals that you were happy to keep the problem earth bound. No protection in a court of law for that. Then you are on your own; a lonely place to be.
