Not really, Mochaman.
WGT need to make sure they implement this correctly.
For example, a perfect way to bungle this terribly is simply to count the number of disconnections, and state them in percentages. That's wrong!
If I launch a multi-player round, and all the fellow players abandon me after a few holes, as is the standard on this site (completed rounds are exceptions from the rule here), then of course I do not finish that round myself. If I am left alone on the course, then I quit as well, because it was a multi-player round I joined, not a single-player round.
WGT need to ensure that when someone is the only person prematurely left on the course in a multi-player match, then such a disconnection is not counted against the player.
Also, it might be worth counting only disconnections in multi-player games, while disconnections in single-player mode might be ignored.
Yet another potential issue is that people sometimes play sudden-death holes, in stroke-play as well, and as soon as one of the players wins the match, they both disconnect, naturally. A way should be found to ensure that such both-sided disconnections are not counted against a player's "karma". For example, let there be a 60-second time-out: if all players disconnect from a multi-player game within 60 seconds, then no lowering of karma would take place for anyone. I'm on the ladders site and have already played lots of sudden death shootouts, and it would be terrible if all these were now said to diminish my completion rate.
