HR Index
How to read this:
• Each row is a park. Filters choose which PAs go into the calculation (e.g. only LHB vs RHP, only June).
• The Metric dropdown selects which outcome is being measured (HR, 3B, 2B, 1B).
• [Metric]% Park is (Metric / PA) in that stadium under the current filter.
• [Metric]% Elsewhere is the same hitters' metric rate in all other parks under the same filters.
• [Metric] Index = 100 × (Metric% Park / Metric% Elsewhere). 135 = 35% more of that outcome than expected; 80 = 20% fewer.
