No problem, Scott. :-)
Actually, it would be nice if we could figure this out once and for
all... Originally, I thought that the first light at the end of the 1/4
recorded your E/T and the second light was used to compute your speed
(average between the two). However, I was later told by a couple of
people at the track that the line is actually between the two lights, and
that it computes the E/T as well as the speed.
I've talked to a guy who was running a Shelby Charger 2.2 turbo against
someone during bracket racing. The other guy was way out ahead of him,
and the turbo had to play catch-up. The other guy beat the turbo to the
first light, but the turbo passed the guy between the lights, and won. I
suppose its possible that the 1/4 mile point is the 2nd light as opposed to the
first one though...
Anyone know for sure? This would definitely be a good thing to know
when bracket racing! (Or any racing for that matter; its always good
to know where the finish line is!) ;-)
