Turns out bitbet.us may actually be in the wrong here! My Little Single is getting 29.4 Gh/s with a firmware update.
In their defense, the bet could be argued to require +/- 10% as delivered (eg, disqualifying firmware updates), but if this performance issue had merely been my software, they'd have defrauded people...
I think you are over complicating it..... The bet has got nothing to do with performance as BFL themselves say on their website that their asic devices are in the final production stage and that delivery is scheduled to start in the second half of April.....
So there has been no delivery of asic devices by BFL yet.... Not to you and not to anyone else....
So the answer to that particular bet is NO
