HD, you 'll have to forgive me, don't worry about too much about my blank profile, just pitch your response at your own level and I'll be happy to pick the bones out of it as best I can.
I very much agree with your summation - in fact I used exactly the same two angles for comparison in the first draft of my last post (comparing legislation via airspace design versus the human factors affecting the pilots in this set of airspace circumstances) but I lost it in the verify login process, and hastily redrafted it. Its good I think that this bit of airspace has perhaps now been "over-engineered" a little in order to compensate.
