Hi Kman,
Players will receive a loss if they quit during a Match Play or Match
Play Challenge game. These are competitive modes where wins and losses
are tallied, so bailing on your opponent 3 times during the same round
will automatically forfeit the game giving the win to the other player.
Stroke play is a non-competitive format in group play right now.
There are no wins or losses tallied. Stroke play is only the player
against the course in an attempt to better their own personal stats and
scoring average. If someone disconnects from your stroke play group
game it will not affect your stats in any way and you'll be able to
finish out the round on your own (or with the rest of your playing
partners) so your efforts are not wasted.
We do have reputation tracking on the roadmap and with its implementation you'll be able to make more informed decisions about who you tee it up with.
