The big question is, over what frequency range and angles does this F?B ratio
hold up?

It is worth taking a look at the Swiss quad described in the Rothammel Antenna
Book, which as far as I can tell was never for sale in English. The Swiss quad
takes the idea of the HB9CV yagi and applies it to a quad to achieve over 30 db
F/B with a lambda/8 boom. I have personally used a few of the HB9CV yagis and
was amazed by their F/B.
The German version of the Rothammel book is available for free online.
