Games-weighted scoring sits 5 pts under neutral
Trend Context: Two different cuts of the same data: each ref's personal over rate asks whether they beat the combined pts in most of their games; the league-wide share counts every game individually.
87 of 139 officials (63%) finish under the 225 combined pts line in a majority of their own games (personal over rate below 50%). Across all 11,979 games, 45.1% cleared the benchmark and 54.9% went under.
