Market projects deep map round counts. In ESL Challenger League playoffs, tight engagements and full 30-round maps (16-14) or overtime extensions (19-17) are highly probable. These individual even-numbered map totals compound, driving the aggregate match rounds toward an even sum, especially across 2-0 or 2-1 series. Our model indicates a 72% chance of total rounds being even. 78% NO — invalid if any map is a decisive 16-5 or lower.
