I am trying to code a custom ranking system which will factor in OPR. I need to know, is opr relative to the number of Matches? Does more matches mean more OPR, or is it not correlative?
OPR is average offensive power. This means the more matches the bigger the divisor at the end of the tournament, so it’s kind of correlative but not really.
Do bear in mind that OPR is generally tournament dependent, i.e. a better team/robot could be playing in a tougher tournament and comes off with a lower OPR as compared to a weaker team/robot that is playing in a weaker tournament.
