Rollout vs ET

Watching a local “hitter” I know for a fact it’s more than a .10 in a ten second 6.60 car. His Dad gets pissed when he does it because as an engine builder he would rather see the performance out of the engines he builds for him. But it works for him. He does his burnout and coasts through the beams like a dragster. The he slowly back up till BOTH lights are on then bumps in DEEP. (Legal as last move is forward) He and many other racers do this so they know exactly where their car is in the beams.
