got to be a consideration if light, on fire, plenty of runway
Maybe I'm not reading your post correctly, but after V1 is reached there is no decision to be made because you are getting airborne regardless. Prior to V1 you can abort and safely bring the aircraft to a stop, but to say to yourself after V1, "gee it still looks like we have more than enough runway, lets disregard that V1 call and keep the jet on the runway" defeats the whole purpose of assigning a V1 speed to your takeoff/data calculations. I can't imagine something written like that in this comapny's SOP's, lol.
Anyhow, I'm sure I misread your post.
