        The queen could never lay in 100% of the avalable cells. There
are many more important factors tha determine how many eggs she lays-
time of year, honey flow, pollen available, temperature, cluster size,
and beed of bee. Of course a brood nest with less space will plug out
sooner than a large one, but is the brood nest really 10% smaller? With
nine frame spacing the cells will be drawn deeper and hold more honey. I
don't know what the relative capacity of 9 or 10 frames is but would
guess its between 90 and 100%, probably more like 93-97%.
