Laughing is good for you but I`m still not laughing. Art may have a
valuable contribution to make. He gave some respectable performance
figures but I`m in the dark on how to reproduce them.

How an antenna`s gain adds up is shown by Kraus in his explanation of
the Deutche Welle antenna featured on the rear cover of the paperback
3rd edition of "Antennas". It starts on page 703 and continues on page
705.
"Solution:
(a) The gain of a single half-wave dipole is 2.15 dBi and of 2 collinear
in-phase half-wave dipoles is 3.8 dBi. The array of 8 such collinear
dipoles adds 3+3+3=9 dB. The reflector screen adds 3 dB more and the
ground bounce another 6 dB for a total gain of 3.8+9+3+6=21.8 dBi or a
directivity of 151 approx."

As for denigration, John D. Kraus was a radio amateur, W8JK.

Why can't you get it thru your head that the antenna
is NOT a Yagi nor does it work like a Yagi.A yagi
is based on coupling that allows for focussing of radiation.
The Yagi antenna is not in a state of equilibrium.
The new antenna is a subject of a patent thus it is not
in your books or any book as yet. I suggest you wait
until it is printed in a book instead of just
thrashing around.
On the other side of the coin, all details are clearly stated
over the past year or more on this newsgroup. Unfortunately
until the term equilibrium with respect antenna elements
which requires understanding not just learning from a book
you are out in left field.
With respect to Kraus you are not a John Kraus
