A .5 "full tree" that has the 3 yellow lights come down one at a time has no effect on ET. The timer starts when you break the beam. You can sit at the lights for 10 seconds and still run the same ET.
A .4 "pro tree" that has all 3 yellow lights come on at once starts the timer as soon as the green light comes on.
