I'm confused. It started out sounding like there will be 3 drivers per team each with his own PT. But then it was mentioned switching transponders. So more info would be good.

More than one car per team racing? This would mean more than one PT which leads you to have to manually add together lap times. Is that really a hard thing to do?

Why not race with just one car/pt per team? I've seen it done where one member is driver, one is a marshal and the third is manning the pit area charging batts etc. Easy to keep track of the laps this way with only one PT.
