breakage
 n.— «Breakage is even more insidious. Breakage is the downward rounding of the odds on the tote board, and consequently the amount paid on winning bets. A horse who may be 5.8-1 will be rounded down to 5-1, a significant reduction. There is no way to tell ahead of time how breakage will affect your bet, but it is more pronounced for favorites than longshots and over time will take another percent or so from your winning bets.» —“An Allegory” by Kevin Depew Minyanville (New York City) May 4, 2007.
