How do I drop a player’s worst rounds from the season?

This is a shared format setting, in the Format & Scoring step (or an event's Settings dialog).

1. Open the Format & Scoring step or settings tab.
2. Find Drop lowest rounds and set how many of each competitor's worst rounds should be dropped from their season total (0 keeps every round).
3. Choose whether it applies to individuals, teams, or both.

This is the setting that keeps one bad night from quietly ending someone's season in week four.
