Being a musician thru formal training from 7 years old - I am familiar with sound engineering and testing-------.

My point on the Caravan was that even well designed setups like the Caravan, often fall into the same deadly trap.
When you trade off an inefficient tho basically more forgiving setup --for higher efficiency- there is always a trade off .
In this case, slight reshaping of airfoil and wing loading increase spells real problems.
On the "heavy" model - where the wing loading is allowed to go too high - the trade off is rapid loss of controlled flight at lower speeds and in dicey conditions - such as cross wing landings etc..
my sound judment and testing procedures are just not along the same lines you learned.
This is probably the worst pun of the year --------------
