Spinex - I think we're talking at crossed purposes a bit. If the thing won't rotate then you have to stop, regardless of speed.
In another era I departed Honiara in a 737 on a black night. Started to pull back at VR but aircraft initially failed to respond. Took a deep breath and tugged really hard on the control column while applying steady back stab trim. Finally the nosewheel lifted off the runway at V2 plus 20 knots.
On arriving at destination, checked the cargo holds and discovered all the freight and bags loaded into the front cargo hold instead of 50/50 front and back. Interestingly, when the trim sheet was recalculated, there was only half a unit of stabiliser trim difference between correct loading and the actual event. Yet it made one hell of a difference in the stick force at VR.
It puts the pilot into a quandary though. If the control column came up as definitely jammed at VR (as against just extremely heavy), then you tried to fix it by hitting the stab trim to get airborne, and that didn't work, you have little choice except to abort and hope for the best.
That is one reason why an intersection departure might save the company money and time, but that extra runway behind you would have been useful if circumstances were such an abort above V1 was needed if the aircraft simply refused to fly. Thankfully these sort of events are one in a million and you hope the statistics are on your side
