So it sounds to me like the answer is to both:

1. Learn to and practice calibrating the light sensors before matches

2. Test/practice under a variety of lighting conditions

 I would GUESS the reason is that the different tournaments have different light set ups.  If a tournament isn't required  to have a certain set up, they may not use and  then you wouldn't have the same results at home anyway, so why give instructions and give ppl a false sense of light certainty.
       The tournament for our area is in a school gym and has ceiling lights 25 or so feet up. It is a well lite room, but not the same as my garage. The different set up did not negatively affect our light sensor, but there should be time to calibrate the robot before the matches- which the kids should do themselves- if you find during the practice round or work table that it is badly affecting your sensor.
Try looking on line for self calibrating light sensor programs?

That seems odd that they don't have the light included in the table building instructions anymore.  We have a light over our table, but we practice at my house, at different times of day, so I don't feel like the overhead ceiling light would be enough to provide consistent light.  The table light makes it so that the lighting is consistent all the time, whether it's day or night.  I also feel like even if a tournament didn't have lights over the table, it's still going to be daytime and probably in a room like a gym or auditorium with bright fluorescent lights.  If you practice in a school classroom with bright lights in the daytime, it may not be as much of an issue.

Our light was simple to build.  My husband built our table and built the part over the top that holds a long fluorescent light, and that was what the instructions said to do at that time.  That was almost five years ago though, so maybe they don't think it's as important anymore?
