Empower Field at Mile High

League baselines are every game played anywhere between 2019 and 2025 (1,960 games), so the comparison is era-matched. A venue gap mixes the venue with the quality of the teams who played there — it is a description, not a measured venue effect. At 5,280 ft the air is roughly 18% thinner than at sea level, which is the physical basis for the altitude claim — this page does not attempt to isolate it from roster quality. Against the real closing total, games here finished -1.15 points on average.
