When a math total has a large enough difference to the posted total, we use the oddsmakers knowledge against them. Because we store each over and under differently in each sport, the over and under angles will have different records, but in reality one could combine them for an overall record. The under version goes under at a rate of 1865-1598-51. Over teams go under at 1202-1008-30 rate. Expected blowouts in games expected to be high scoring goes under 457-347-11.
