j.t.
It comes down to a case of risk assessment and management. Nothing wrong with the basic philosophy but the use of a few more knots, especially if the runway is not critically close in obstacle limited .. just might make the difference between a few beers more than usual in the bar that night .. or not needing the beers at all.
Such as a takeoff in an L1011 on KJFK's Runway 13R (14,500) going to the other coast. It was raining hard (not TRW, rather a March 'noreasterly) with surface winds gusting to 50 knots and 100 knots reported at 1,500.
A very slight climb until V2 +50 then up into the muck.
