Tim,
I think you should consider there are other factors that cause the NXT to be slower
than the RCX. You may not be able to accurately run this speed test, until the NXT
shipping bottleneck is eased. I assume that will be sometime next year. I suggest
you run the test again, then. Maybe several times.
Also, I suspect your NXT will travel over water. That's something your RCX may not
have done during your test.
Actually, I have no idea if there is a shipping bottleneck, but if the problem
continues, maybe you should re-run the calibration program. It's possible the light
sensor readings are different enough that it's having a hard time detecting your
door, because it was calibrated before crossing the water.
