100% agree, but I also wonder why the f some people are so (apparently) aggressive with their rotation? IMO, if you were to, let's just suppose, push with erroneous numbers, general experience flying airplanes should prevent one from blindly continuing that 2-3 deg/sec rate when the airplane isn't doing the normal things and banging the tail before you realize it. I'm sure the training dept doesn't like it, but just like every other airplane I've flown, I do a mini rotation, wait for the wheels to get light and to feel the wing actually flying, and then I re-apply that rotation/pull. If my Vr was 20 knots slow, I would delay that second rotation until I felt the wing flying, just out of habit, and not bang the tail I don't think. To hell with the TERPS/second segment numbers at that point. Granted I've had like one rotation in my whole time flying this hog, where it just did its own thing, uncommanded, probably a gust of some sort, and I had to apply forward pressure to stop it, while the CA just assumed I'd f'd it up. But that isn't what we are really talking about with tail strikes I don't think. And it was easily fixed well before that happened, in my case.
