The advanced stats quick link on the Scoresheet page allows scorekeepers to track additional player stats that are not in All-Star Rec Manager by default.
Stat categories are customizable on the Preferences page, League tab, Stat Categories section.
When you click on the Advanced Stats quick link, a popup window will open with an advanced stat table for each team. All advanced stat categories will be setup as separate columns with +/- buttons to add or remove a count from the stat for the player. These stats can be pulled as reports.
