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 1741-1349-88. It is 30-21 this season including 15-7 last 22. When combined with a previous total compared to the current total angle, it goes under 265-147-21 for +103.3 units and a 22.8 ROI.
