I have no idea on the algorithm and all of that stuff (pretty sure it changes game to game?), but I do know they post the standings on the USFIRST website under that particular event.

go to that link, pick an event, and there should be a row with a link to the standings. They update just like the ones in the pit, but no more running back and forth.
