 The reaction-time counter begins when the last amber light flashes on the Tree and stops when the vehicle clears the stage beam.

I take this as the prestage light turns off (starting the clock)and then when the staged light turns off (stoping the clock). Then the difference the computer calculates you left before or after the green light was turned on.


Not the pre-stage, but the last of the three yellows that light just before the green is when the timer starts.

I read it the same way.

No you didn't explain it wrong. I know that the stage light initiates the time.

Why brought it up in here is that two weeks ago in time trials we came up with a off the wall  red light, a .430.  It is possible to pull the front wheels out of the stage light. Because this run also gave us a slower '60 time, but the car seemed to hook really hard. Also this is after I was getting on him about staging as shallow as he could possibly get. And he is running a pretty small front tire which may have contributed to it. It only occured once and never changed the delay box at all. And he is still cutting .510-.520 lights during the day and .498-.510 in the dark. Without adding anything to the box. So as night nears we are going to add 10 to the box.

I'm going though this with my son right now. When he has bad lights he runs 14.70's when his lights are good or red he runs 14.60's.

If you go red and your time slows down, you were staged deeper than normal. If you have a slow RT and you have a faster 60' then you were shallow staged.
The RT and ET timers have nothing to do with each other. It's just the little bit of head start you have going shallow. Those couple of inches can make a big difference, (That's what she said  ;-) ).
