Is the qualification match robot randomizer really "random"

The 2007 algorithm was seriously flawed that year, and vastly different than the algorithm used in any other year in FIRST. That year, one team was randomly chosen from a low group of team numbers, one from a middle group of team numbers, and one from a high group of team numbers. As a result, there was a much more limited sample size of available teams in the algorithm, leading to match schedules with many of the same teams constantly playing with or against each other, and no one else.
