For those making the argument (mostly satirically so) that week 4,5,6 regionals have an advantage over 1,2,3, remember this. All robots in 1,2,3 had the same (dis)advantage of not having that hour for calibration. All robots in 4,5,6 have the same (dis)advantage of having that hour. Each regional was fair in and of itself; the winning alliances are true. No robot in a regional had an advantage over another robot in that same regional due to the hour of calibrations.

Likewise, no 4,5,6 team will have an advantage over a 1,2,3 team because the Atlanta field lighting will be different from all regionals. Teams will still have to calibrate to Atlanta conditions, no matter what or how many regionals they attended.
Similarly, I don't think rules imposed by head ref(s) at any particular regional had an adverse effect on the outcome of the event. All teams in a regional had to play by the same rules (misguided as though they may be). Only when one team experiences intentional favortism over another due to intentional inconsistency of judging calls does one team profit while another suffers.

[for what it's worth] I think FIRST has done a great job of showing they acknowledge they can make mistakes, and they are willing to analyze and possibly fix those mistakes if possible. Let's just hope we don't get Update #26 during the championships.
