What he means, as evidenced by his earlier posts, is actually closer to "margin for error". If you don't place your holes right--say, off by 1/4" in a given direction--belts may be close to impossible to get to work. If you can't handle the risk of being off by 1/4" routinely by adjustment in the belt tension or length, then maybe belt isn't the right choice. OTOH, if you can, then it's something to think about.
