Okay, you yous guys got me thinking. And then we discussed it at work.
With a wire synch times on the wireless equipment every hour or so and
you're in the .001 ~ .0005 range. Then store the time for each start and
finish on the start and finish units. A few seconds after each finish
the finish line forwards it's time to the main system and asks the start
for it's time.
The displayed time would be a few seconds after any given run, but would
be really damn accurate.
May want a volunteer to code it though and it would take some time to
write. Hardware wouldn't cost much though.

Something like this would work if a single trigger is used, but only one
car could run on the course and the entrance/exit would have to use the
same "lane".
But for a dual setup.. one start trigger and one finish trigger to allow
multiple cars on course with start and finish triggers in separate
locations, an accurate connection would have to exist (wires) between
them since the important timing separation is between start and finish
triggers. Then you could use a wireless device to transmit that data,
but that would take away the benefit.
In the future, there will probably be time signals over the airwaves
(does GPS do that?) so you could have multiple wireless timers spread
throughout the course and get accurate start/split/finish readings. Now
that will be cool. How do they calculate split and gap times at race
tracks that F1, CART, and IRL use?
