Lots of this stuff is for back in the classroom & CRM etc. What should come out of it is that V1 is the line. Stop before, go after. End of. Sim should then re-enforce so that, really we get into an action for all cases. No discussion. Longest runway in the world, no obstacles in front or behind, V1 occurring with miles of concrete in front (?)- STOP for heavens sake because that is what we do all the time. Next day, you could be on a very limiting & challenging set of conditions. Up to 80k, stop for anything, even uncontrollable flatulence , 80-V1, only for well specified and briefed circumstance, after V1....................go...................pleeeze !
