the math says the same thing I was harping on -
CG really does not affect wing loading -as it is commonly addressed .

CG does however - affect the total drag ( efficiency)of the aircraft - and the interpretation of that effect -is where I ,personally don't subscribe to the "increased wingloading " analogy.
Call me picky---Most of what I have learned about the CG shift --comes from spending hours flying pattern models I designed and marketed for years .
In my ongoing search for truth-I found that a lot of the "factual" info about aerobatic model design -and some "rules"- just plain bunk.
The reasons why certain designs tucked or yawed or dove or twisted - were not peculiar to a particular design but were simply due to these designs being setup incorrectly.
A very forward CG (10%) for example - made for a very good high speed model - it was easier to hold in a predictable line
Conversely a very aft cg (30+%) worked great on lightly loaded, low speed models
extremely agile.
