PINK, iirc from DC, was geared for 12 ft/s after friction. They traded the extra speed for more torque so they could go to a single-speed drive without the worry of being pushed around most of the time. This tradeoff was obvious from just a short conversation with them, so I'm not deducing it deduced so much as I'm re-stating it. Only they can say how much they felt they were pushed around this year since video seems to be rare for 2011. For the first 0:45-ish of the 3rd Finals DC match, we totally shut them down*.

*Then our chain broke, and all of the coulda-shoulda-woulda's set in ... lessons learned for the future, heh.
at champs we went down to about 7-8fps, but the ratios weren't our only problem earlier on. our arm was still geared waayyyyy to high. it was about 1 second to rotate from collecting on one side to collecting on the other with a single banebot. as a result power and acceleration seemed to tank when the arm was moving about (which is ideally quite a lot).

in the end we just weighted up to 120 and geared to be traction limited because we don't like getting pushed around
