A great example of this was a heavy A330. On a long runway, the V2 could be some 20-25KT below Vfe F2. Guess what happened on a windy day - during takeoff in a gust speed would jump towards Vfe and people would pull the stick and over-rotate, at high rate cos they were scared of overspeed. But when I suggested using 1+F the answer was invariably 'noooo, F2 gives better tailstrike clearance'
