Always gross, since the targets already allow for handicaps. Every player earns points on every hole: Albatross 8, Eagle 6, Birdie 4, Par 2, Bogey 1, Double Bogey or worse 0. Each player chases their own quota target, set from their handicap (often 36 minus course handicap over 18 holes). A player's +/- is points minus target, and the team with the best combined +/- wins.
Before you tee off: set everyone's target under Point Quota Players. You can set your own, a Captain can set their team's, and the Commissioner or a Group Manager can set anyone's. Each box suggests a target from the player's handicap. A player with no target counts for nothing in the result.
Entering scores: on each hole pick what every player on the team made (Par, Birdie, Bogey and so on) and tap Post Team Hole Scores, which turns on once every player has a score. Pick a posted hole to fix it. While play is on, the scoreboard and chart measure each team against its pace for the holes played so far.
How it ends: tap End Match once every hole is posted. The best combined +/- wins.
