How about dropping the ax you are grinding and learning some basic aero?
The "overall elliptical sum" is NOT a false premise. It is also a
"CFD-based musing". This dates back to the 1920s and people like
Ludwing Prandtl and Max Munk.


Those studies were not of, did not consider, and do not apply to
canard aircraft with winglets.

Your arguments are ancedotal. Mine are engineering based.


The correct term for an argument based upon verifiable real-world data
is "empirical", not "anecdotal". My argument was deliberately
empirical. When engineering analysis doesn't jibe with reality, I
choose reality as the final arbiter.

Show me a canard Reno racer that has ever won a race.


To my knowledge, the highest placed canard aircraft (*) at Reno was
David Ronnerberg's Berkut which finished second place among six
Glasairs in 1999. The first place Glasair III was 9.4 mph faster than
the Berkut and the Berkut was 11.9 mph faster than the third place
Glasair III. Although the Berkut did not take first place, its second
place showing remains a valid example of a high canard placing among
non-canard aircraft. Thanks for helping to reinforce my point.

* The purpose-built screamer "Pushy Galore" had a small canard but
also a T-tail.

These studies apply to ANY arrangement of lifting surfaces. Even your
idol Burt Rutan uses them.
