User requirement: Only 1 player with -6 arm, no more than 3 with -5 arm
2005 tz_runs_total data analysis:
- 23: Jim Edmonds (1 player)
- 21: Carl Crawford (1 player)
- 19: Coco Crisp, Brady Clark, Andruw Jones (3 players)
- 18: Cliff Floyd
- 17: Jason Michaels, Ichiro Suzuki (2 players)
Updated thresholds:
- > 22: -6 arm (Jim Edmonds only)
- > 19: -5 arm (Carl Crawford only, satisfies 'no more than 3')
- > 16: -4 arm (the three 19s plus 18s and 17s)
- Graduated scale for remaining tiers
Result: Elite arm ratings are now truly exceptional and rare

The arm_outfield function had thresholds designed for bis_runs_outfield,
but retrosheet_data.py uses tz_runs_total (different scale).
Issue: 20 players had -6 arm (top rating) - should be exceptionally rare
Analysis of tz_runs_total distribution:
- Ranges from -8 to +23 (not -10 to +10)
- Old threshold: > 8 gave 20 players with -6 arm
- New threshold: > 18 gives ~2-3 players with -6 arm
Updated thresholds to properly map tz_runs_total values to arm ratings:
- > 18: -6 (exceptional, top 2-3 players like Andruw Jones)
- > 14: -5 (elite arms, ~5-8 players)
- > 10: -4 (very good)
- Graduated scale down to +2 for very poor arms
Result: -6 arms now truly exceptional, proper distribution across ratings
