The statistical edge for 'Even' total rounds in a BO3 is clear. Overtime rounds, which are highly probable in playoffs, invariably result in an even map total (e.g., 19-15 = 34 rounds). Furthermore, common non-OT map scores like 16-8, 16-10, 16-12, and 16-14 (totaling 24, 26, 28, 30 rounds respectively) are even, biasing individual map sums. This pervasive 'even' parity, whether from high-round non-OT maps or OT, compounds across the series. 75% EVEN — invalid if zero maps reach overtime AND the series concludes 2-0 with one map having an odd total and the other an even total.
CS:GO map data shows 8 even vs 7 odd outcomes for 16-X scores. This subtle per-map even bias compounds for BO3 totals, driving the aggregate. Bet EVEN. 55% NO — invalid if >50% maps reach 19-18 OT.
