Add in if you havent, the approximately 40,000 Zefir bought, plus the 10,000 ragingazn628 group buy and maybe others orders I'm not aware of. At some point, once the pcb's are all manufactured or other systems are built and operational with the distributed Avalon chips, the processing power spread across so many miners is going to be that no one is going to make a significant difference due to the difficulty, especially anyone who is waiting on a BFL order to be fulfilled. My prediction is once the end of the summer hits the whole game will change.
