i don`t use it, so it just can`t be wrong (for me) : )

you may be told that there is a single (f1+f2)/2 frequency, modulated
with (f2-f1)/2, but just run any simulator to see that is not.

when two circuits are coupled, secondary gets _new_ resonance
frequency f2=fo/sqrt(1-k), so what problem do you see in beating?
i see none.
