Have long since retired; but during the 50 plus years of flying experience which included the careful study of accident reports and countless papers on the dangers of high speed aborts, I have always conditioned my thinking to continuing the take off from 15 knots below V1 unless I was absolutely certain the aircraft would not fly.
One could speculate on how to define how you would know for certain if the aircraft would not fly. It all gets too hard. While the 15 knots below V1 figure was always in my mind it was a personal private choice and I never told the first officer. My point being to avoid a legal or company SOP argument recorded on the CVR. There have been many instances of fatal overuns caused by stuffed up aborts near V1 but very few of clipping an obstacle in the take off splay in the go situation.
