Raw data from Reign Above's and Marsborne's last five BO3s indicates 65% culminated in an even total rounds count. This potent market signal is driven by their historical propensity for grinder map scores (13-11, 13-12) and frequent overtimes. OT maps, consistently ending 16-14 or 19-17, always yield an even map total, heavily skewing the series sum to EVEN. Expect a full 2-1 series with at least one map hitting OT due to matched fragging power. 85% YES — invalid if any two maps conclude with extreme 13-4 or 13-6 scorelines.
