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 over version goes over at a rate of 881-666-27. Comparing current total to past total(s) goes over 279-212-4. When both apply, it goes over 60.3 percent. We have a sub-angle system of one of the above that is over 189-112-4.
