Make each class a heads up run against the current index.

A/S 11.25 vs A/SA 11.30. Just give the Automatic .05 head start at the tree and then run to the stripe.

or run all class eliminations on a .500 pro tree and let the driver have more involvement in the runs.
You can make up a tenth on a pro tree, but not on a sportsman tree.
