.........yep! you don't start getting timed until your car crosses the green light. So the driver next to you can leave and finish ahead you but you can get a better quatermile time than him/her.

It depends on the track and the setup, but generally on TnT days, that is the case. It's a .500 tree, with .500 seconds being a perfect reaction time. Anything .499 or quicker and you've redlighted, .501 or slower and you're sitting on the line too long. Some tracks list .500 as .000 and any negative numbers are redlights.
There are also .500 and .400 pro trees, where all the yellows light together and then the green lights immediately after. If you've never raced on one, you can see them on all the pro drag racing TV coverage. Very difficult if you're used to standard .500 trees
For me, on TnT days, I concentrate on my launches and usually end up sitting at the line for a full second or longer so that I can get my launch RPM right before dropping the hammer. Someone who doesn't spend a lot of time at the track may have a quick reaction time, but different cars react differently and can take several tenths to break the beam (shallow/deep staging makes a big difference here, too).

For test and tune the RT means absolutely nothing, it only comes into play in NHRA sanctioned competitions or organized bracket racing competitions.
In other words, if you are going to the track for a "run what you brung" don't worry at all about your RT, only you ET and trap speed.

I'll have to admit that I've yet to run into a pro tree at a Test n Tune. You must do it a bit more serious than others.
I've only done New England, Atco, Valdosta, Orlando, No Problem, and Gainesville. At those few tracks, RT is listed from .000 with that being the perfect light. I was simply sharing from experience that the light does not change the ET and a .1 is not a fast reaction time at the strip. Do you differ? If so, then break out the wallet and let's bracket.

I belong to a national, Internet based, car group that has a race in the MidWest each year. I organize the drag race portion of our event (we road race, drag race, autox, car show and 0-100-0 at the 3 day event) and our quick 8 drag races run on a pro-tree.

No argument there. If you're not running in the low .5XX range (.550 or quicker), you'll end up on the trailer
