If I’m not mistaken and maybe I am, the clock starts when your tire leaves the second ‘Staged’ beam right? So, staging shallow plus the distance between the two beams would be a lot more than 6 inches wouldn’t it?
Only one beam, the second one, first one (that means nothing) shows you’re getting close to the second so you don’t have to inch along four feet away.
What gripes me are these pit members who motion the driver forward to the PRE STAGE bulb, can’t the idiot driver SEE when the bulb comes on? This cr@p takes 10 minutes for nothing! Roll foward till the pre stage bulb lights, rev the miss out then stage on the second, even a cave man can do it
