With the new version of leagues (rolling out now, send me a message if you want opted-in), we now support TDs editing starting scores in the Tools for the event. Players can still choose their own starting score when they create their card, but each player’s starting score (aka “adjustment”) will can be edited directly by the TD and viewed by everyone on the leaderboard.
From the Admin Leaderboard, click the pen icon next to the player’s scores and select “Adjust scores and penalties”.
Then you can change the starting score (or make other hole score or penalty adjustments like before).
