I don't know the reference, but apparently someone (I think it was Huber) confined bees and fed them artificially, and then weighed the amount of comb produced. This led him to the conclusion that it took about 6lb of honey to make 1 lb. of comb, though he thought it might sometimes take a bit less. I don't know where the higher estimates come from. It's obviously a very artificial situation, and one might wonder whether the same ratio would apply in real life, but like you, I have problems in imagining how else to do it.
