A repeatable minibot for 2011 would have been good at Granite State Regional (53 teams with a lot of high quality teams).

Quarters 1 often give good insight as you have #1 alliance against #8. #1 seeded highest and gets 1st pick. #8 was the quality of the lowest ranked captain and is picking what should be roughly the #16 best robots at an event. since they are the last captain, the teams they are picking can't say no and still compete. Seeing what makes up a #8 alliance is to me a good indicator of what it takes to be a Captain and to get picked at an event. If you watch the quarters at this event, a repeatable mini-bot (as long as it makes it up in scoring time) would have been a good pick.
New Jersey, a 64 team event would seem to confirm the same logic:

At a qualified event like MSC, MAR Championship, World Championship, an MCC will likely run in to more difficulty, but those are distinctly different then the stated goal of playing in Elims at District or regional events.
