Wagner,
I disagree.
Like someone had posted earlier today (sorry, i don't remember!), the
composition of the switches, spring constants, etc, add more variables
to the scenerio.  So (as quoted earlier today), the person who may know
the answer first, and pushes the button in the SAME INSTANT (within
microseconds) as another player, and even having top priority, still may
not get it.  Plus, I was in quizbowl for my entire high school career.
Their systems cost A LOT of money, and i wanted to build one for cheap.
very rarely did i see two lights on at the same time... indicating two
people were within that margin of time to do that (this can't even
happen with the encoder design ... just showing how often that scenerio
would happen)
