Re: Blue Wins
The red lights around the plates emit heat (IR radiation) that heats up the carpet underneath the switch. This heat rises underneath the switch causing it to be pushed upward ever so slightly. Similarly, the red lights under the scale will produce heat that causes the red side of the scale to be pushed upward slightly.
When either the switch or scale is close to evenly balanced, this effect will favor the blue alliance and when taken in aggregate over a large number of qualification matches, this results in the blue alliance winning a disproportionate number of matches.
The Coriolis effect also factors into this, but I will leave that derivation as an exercise for the interested student....
