It's always surprising in life when you realize that something causes the opposite results that you expected. Tighter spacing makes frames easier to get out as they are flatter and not as uneven. Looser spacing makes them harder to get out as they are uneven with honey protruding which then catches bees and rolls them.
"...if the space is insufficient, the bees shorten the cells on the side of one comb, thus rendering that side useless; and if placed more than the usual width, it requires a greater amount of bees to cover the brood, as also to raise the temperature to the proper degree for building comb, Second, when the combs are too widely spaced, the bees while refilling them with stores, lengthen the cells and thus make the comb thick and irregular--the application of the knife is then the only remedy to reduce them to proper thickness."--J.S.
