The members of team IFI were plenty dominant prior to organized collaboration. It should come as no surprise that they continue to do so when working together
Here's some food for thought:
I looked at all of the Regional and District Event winners so far this year, and the #1 seeded alliance has won 64% of the competitions thus far. In fact, only once by my count has an alliance seeded worse than 3rd won the event (I apologize, I don't remember off the top of my head which competition that was).
I haven't had a chance to see how this compares to data from years past, but it seems that in 2010 more than ever the high seeds are winning (for example, team 341 has won 4 regionals in the past 4 seasons, and only once - this year - were we the #1 alliance).
IMHO, the field of really effective robots at most events thus far has been fairly shallow; only a handful of alliances seem to end up with prolific scorers and they tend to run away with the trophies. These teams are also aided by the seeding system this year - more than ever, I am seeing #1 seeds that are fairly predictable.
