Heads up is a money sponge. However, an idea would be to make the breaks pretty tight i.e., 9.00-9.50, 10.0-10.50 (.50 steps) then turn the tree into green start. This is where the timer starts when the green comes on, thus allowing the lower dollar cars, and drivers who can't go .400 or .500, to figure out where they fit, to compete with the higher dollar, harder leaving money sponges. Since your reaction time is now included in your dial-in, er, I mean your "index", the whole field should tighten up considerably. Me, too much bs, I'll just scribble a different number with my sharpened up shoe polish.
