I notice that CIA B and AEPI A were both DQ'd this year for five second violations.
2009, it was Fringe D
2008, Pika C, Phi Kap A, and SDC D
I could probably keep going...
What is the point of trying to bring your buggy out so late, that you sometimes don't get there in time? Bring it out 1 minute before and let it sit there. Unless you're really trying to maximize--perhaps with your top 5 team (which none of the teams listed above actually need to do), wouldn't it be better to have a time that is .1 seconds slower because the wheels are cooler or something than to have your hard work DQ'd?
I assume 1 or 2 of these are from extreme circumstances (mechanical failure or something). But I imagine some are just plain unnecessary because the team wants to maintain the image of bringing buggies out late.
