Upsets of the 2+ level are very rare. However, more common (tho still a small %) are 3 setters where the higher player wins with a 2.0 difference. I have seen several of those reviewing ITA summer circuit results. Most of those are players with UTR under 10, but a 12.59 barely beat a 10.51. That's big but it wont count. However, even if the 2+ wins by lower level players do count, what is the weight? Even matches 1.0-1.99 apart carry less weight, than matches 1.0 UTR or less apart. Would be helpful to know the weight. At these ITA summer circuits, there are some big gaps. If a match only counts .25 or .5 of a 1.0 gap match, players should know so they can choose to play tournaments where they will get the maximum credit for their matches. Why play 5 matches if players will only get credit for 2 which has happened in some past ITA summer circuit matches.
