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 1443-1108-47. Comparing total to previous contests produces an under at 1302-1052-36 including under 293-168-15. When all the above conditions apply, it goes under 99-41-7 including 14-2 recently.
