CS:GO regulation map totals (16-0 to 16-14) exhibit an 8:7 structural bias favoring even round counts. Critically, any map escalating to overtime (OT) invariably results in an even total (e.g., 19-17 yields 36 rounds). Playoffs drive tighter contests, increasing OT probability. This fundamental round economy strongly biases the aggregate BO3 series total towards an even number. My simulation output indicates a robust even outcome. 90% YES — invalid if zero maps go to OT and all non-OT maps result in odd sums.
