Anyways, we replayed two of our matches, still losing one and winning the other, when the other team complained of lag or lack of comm.
Interestingly, we experienced jerkiness during these matches, but were never as severely affected as other teams, some of whom did not move. Also, in eliminations, our alliance captain lost communication multiple times. Luckily, we were able to narrowly upset the second alliance, but were defeated in semi-finals by a single autonomous frisbee in both matches.

The bandwidth limit is published as 7mb/s, but that's for all communications for each robot. It's possible that with the camera at 5mb/s, the rest of the robot communications was putting it close to 7mb/s.
When you say that other teams were more severely affected, are you implying that other teams in the same match as you (including ones without cameras) were having more severe lag/comms problems, and that lowering your bandwidth improved their trip times?
