The bitbet one was clearly won by those betting against BFL. It only allowed +/- 10% of hashrate, which BFL has failed to meet so far.

Although... I'd have expected a competent judge to contact me and ask my opinion on whether the device is capable of the 27 Gh/s required, in case my current results were the result of software issues. But it's immaterial, since as best as I can tell so far, I'm getting the most performance out of it that it can handle.
