Isn't this all getting a bit silly? I think we can take it that the aircraft has passed V1, therefore the stop scenario doesn't apply. It's probably past Vr as well, and still accelerating, so in the case of an engine failure has kinetic energy beyond that required at Vr. Yes, it was a late and slow rotate, for whatever reason, but not dangerous, and certainly not warranting the analysis going on here. Then, what do I know? I'm just a retired airframe driver. Ask the crew.
