Oooooooh dear!
If this is the standard of "instruction" or the current way of "imparting knowledge", then gawd help us all.
A simple posting on a simple aerodynamic quality descends into a personal and adverserial series of criticisms of others attempts to answer the OP.
Tommoutrie, I hope you are not a training pilot or ground instructor of any type as I can see the lessons being excruciating and counter-productive.
If that's personal/adverserial then so be it, I hold my hand up and admit it, but I can hardly seee how your contributions are helping.
Maybe stay your hand on this one and allow the discussion to proceed productively?
