I'd say not so fast aviators'. At Vr there should be a three second rotation to T/O pitch attitude and V2 about the same time. Every tail strike I have ever investigated showed rotations to takeoff attitude of around two seconds. Some of the problem comes from new guys with just straight wing experience. The second comes from light weight takeoffs where one can really just jerk the airframe airborne.
Go back to the F-86 in the 50's. Guys were literally rotating and running off the end of the runway. Most had transitioned from the P-51. Bob Hoover went over and demonstrated how it was done. He would land, stop and do a 180 and take off down wind without a problem. Lesson learned.
