Mining difficulty also jumped within the last day right?
The hash rate did jump, but it isn't because of Asicminer, because hash rate is calculated from blocks/s, and since the difficulty readjustment, Asicminer has not mined any blocks, therefore is not the one contributing to the hash rate calculation.
I think that what unlimited_power says is that now, with the difficulty readjustment, the boost we had could have become not enough to get a new block that soon; not that AM had contributed to that difficulty readjustment... So, if our 5 blocks found yesterday were due to an increase of hashing and not just good luck, the new difficulty could be avoiding us to get a new block yet. (I suppose we will se in a few hours)
Or maybe, it could be real hashing power that has been already taken offline, as someone points...
