I should probably explain -- and this might explain the whole difference 
between our observations -- that the times when I saw 30-35% drone comb 
with no end in sight, I didn't let those drone frames hatch out, so 
although I was seeing a huge amount of drone brood, I was keeping the 
number of actual hatched out drones very low.  If I were to let all those 
drones (and mites) hatch out, perhaps I might then see a much reduced 
tendency to draw further drone comb, more along the lines of what you're 
talking about.  I don't know, and I can't see wanting to test the theory, 
because it seems like really poor management of the varroa situation.

I find the way that small cell theories intrude on every conceivable 
thread extremely tedious.
