I wish i had not written the "i hate" part of my first post. To sound arrogant or provoke anyone was not my intention. It has also caused this thread to drift away from the topic.
John_T: You seem to be the first engineer on this thread. A couple of questions; Isn't a "drag bucket" on the drag vs alpha curve rather normal on modern airfoils? As far as I know this does not imply that there is a "bucket" in the drag vs airspeed curve. The way I understand the "pro step" people, they argue that there is a bucket in the drag vs airspeed curve giving lower( or perhaps equal) drag as airspeed is increased. Have i understood things correctly?
