I taught my rotation rates were normal until I saw a video of one of my takeoffs on youtube. The tail got closer to the ground than I would have liked and I counted the time it took from nose wheel liftoff until what looked like 15 degrees nose up, it worked out to be 3.5 degrees per second! Since then I have slowed it down and I use the PFD.I now feel I have much better control than when I look outside. Maybe I'm just odd
