This page shows how much extra distance a park provides to baseballs hit within these specific parameters, chosen to provide apples-to-apples comparisons (better than just “home runs”) and to minimize the effects of spin, slices, or spin: Batted balls hit 90+MPH, at a launch angle of 24-32 degrees, and pulled at 0-24 degrees (where 0 is dead center and +45 is the foul line). This helps show how a ball flies at each park given identical launch conditions.
The total distance added is broken down into these sub-factors. Temperature (every 10°F adds 1% distance); Elevation (every 800 feet adds 1% distance); Roof (adds 1% distance); and Environment (everything else not otherwise captured, like humidity, wind patterns, etc.
