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 1450-1190-55. This includes 293-155-13 since 2014 and a stunning 22-4 this season.
