All of this debate is theoretical
My contribution certainly isn't. My initial goal was to establish what *I* am capable of in *my* plane. Which I have now done. I agree that it is all type specific and pilot specific. I would not expect to get the same results in the Pitts or in a motor-glider, to take two extreme cases. I have also established experimentally, for my plane at least, that the Rogers analysis seems correct in practice.
And also had a couple of interesting and enjoyable flights. Not much theoretical about all that.
