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 784-477-34. Another angle compares current total to previous totals of each team and is 467-307. When both apply, it goes under 192-91.
