Not at the moment. Several TDs and Marshals for big events have learned how to set up live scoring and do it during the rounds. That's what you've seen on the PDGA website when it's done at Worlds, NTs and a few other Majors. It's not hard to do but access to the score uploading area is restricted to TDs with their event password. Plus for now, Gentry has to place the Live Scoring link on the home page when someone wants to do it so people can access the live scores.
This process will have to be simplified and structured for safe access by mobile apps and players who have Smart Phones to enter live scores for their groups. I think the goal will be to have a better system by 2012 in tandem with the potential approval of the use of Smart Phones during events in 2012 mentioned in my previous post.
Rater of the tossed arc.
