Staging light on off interval question
I know the delay between the third amber and the green light is .500, but my question is: Is the third amber on for .025 and then off for .025 and then the green comes on? For example, if you wanted to leave when the second amber goes out, is that .750 before the green comes on?

Thinking outside the box? I deep stage and if I jump on a flash instead of "waiting" for the 3rd amber I'm -.025 to -.035 (very red). My shallow shaging racing buddy decided this week to leave when the second yellow went out. His reaction time droped by .025 to .035. Put his RT's into the .00x to .01x range. I'm guessing that's what your asking.
I believe most using a delay box go off the first bulb not the second. Gives a "true" reaction as you don't look at any lights comming down.

I read about this on another bracket-racing Forum, and it really made me think twice.....
the subject in-question was how to foot-brake an EXTREMELY slow-leaving car, a car so-slow that deep-staging and leaning on the converter as-hard-as possible stillresulted in very-poor RTs
(I have a Cross-Fire in an '82 Corvette that runs 2.3-2.4 second 60' times, even-with 3.73s gears, so I read with interest ):
a very-good bracket racer said he'd had sucha car once, and here is how he staged & launched the car.....
He staged (both-bulbs lit ) with his RIGHT-foot on the brake-pedal, and with the motor at-idle, he simply 'swapped-pedals' at the flash of the SECOND-bulb, mashing the gas with the same foot:
since he had practiced this method for a few weeks, and on his practice-tree, he could routinely get .02-.04 RT from a car that would go no-quicker than .08-.10 deep-staged.
I have since given-up on the '82 until it is more to my-liking, but somebody who has the desire & discipline could use this method to his advantage.

To the OP each light is .500 apart, all I can say is it is on for most or all of that and the next lights up *** soon as the previous goes out.
When I foot brake a street car I leave on the last yellow.

I tried another trick but could not get it to work...this one is where you hold your foot about an inch or so above the gas pedal and drop the hammer from there....this helps if your spot is a hair too early...

maybe he passed it along to you?
I think the guy who mastered that technique realized that in the time it took for his Right-foot to go from applying the brake-pedal to mashing the gas was about the proper delay to leave on the 2nd bulb, but if you have that hesitation fixed, I doubt you'll need that-much lead-time

I fixed the guy's with the delay boxes last month,I set .007 into the tree and they are still tring to figure out what happened.
21 red lights in the first round.
This month I am going to set up the tree for a 7 second count on the pre stage light.
