+# Bug: pd-cards retrosheet --season-pct Ignores Script Config
+
+## Problem
+
+The `pd-cards retrosheet process` command defaults `--season-pct` to `1.0`. In `pd_cards/commands/retrosheet.py` line 108:
+
+```python
+rd.SEASON_PCT = season_pct
+```
+
+This unconditionally overwrites whatever `SEASON_PCT` is set to in `retrosheet_data.py`. If you don't pass `--season-pct` on the CLI, the script's value is silently replaced with `1.0`.
+
+## Symptom
+
+Dry run output showed `Season %: 100%` even though `retrosheet_data.py` had a lower value configured. This revealed the issue.
+
+## Fix / Workaround
+
+Always pass `--season-pct` explicitly on the command line for PotM runs:
+
+```bash
+# July PotM: 31 games / 162 season
+pd-cards retrosheet process 2005 --cardset-id 28 --description "July PotM" --season-pct 0.191 --dry-run
+```
+
+## File Reference
+
+`pd_cards/commands/retrosheet.py`, line 27 (default) and line 108 (override).
+
+## Impact
+
+PotM cards would get inflated stats if run at 100% season when they should reflect a partial month of play.
