There should only be three photo-sensors at the starting line, pre-stage, stage , and over stage

Only 2 photo electric cells perform the stage function. Prestage is just a warning you are near the fully stage position. Stage lock is part of the computer program the way I understand it. I do not like the blinking stage light and lost several times by being late or red because of it. Once in the final of a National Event due to that happening. Not my light blinking, just being thrown off by it. I can not ever remember blinking my stage light in 30 plus years of doing this. Once the fully staged light comes and goes out the next function should be a red light however, that is not the way it works all the time. NHRA should figure this out at all the tracks not just some of them and be consistent with its implementation across all the tracks/events. For all the event not just part of it.

There are four sensors on the starting line. Prestage, stage lock, stage, and over stage or guard beam

Back in the '80s, the tiny front tires of my Pro ET rotary Mazda sometimes wouldn't light the pre-stage and stage lights at the same time. Probably a set-up issue with the photocells, but it used to piss me off- I would stage as shallow as I could, and would get called on the "no deep-stage" rule. I would have to back out and re-stage, to demonstrate that it was their equipment, and not my car.

At least, now I feel I understand what is going on and can determine when I have made a bad run and when the timing says has given me a bad run.
