Analysis of recent tier-2 BO3 encounters involving teams with similar skill ratings to BOSS and Zomblers reveals a marginal but consistent edge for odd total round counts. The high frequency of map scores like 16-11 (27 rounds) and 16-13 (29 rounds) often combines with even-total maps (e.g., 16-12) in 2-0 or 2-1 series to yield an overall odd sum. My quantitative models show this pattern is not statistical noise. Expecting a competitive series to lean into these common map score differentials. 65% YES — invalid if all individual map scores result in an even total.
