Hash rate drop

44 Th/s drop the past few days.  Difficulty estimate for next readjustment is to stay the same or go down slightly.  Speculate the cause and the effect!  Go!

Edit:  44, not 4... duh

Thanks for that.  It looks like about 20 can be attributed to AM.  The rest may be variance then?

Difference between mining power and its average value is something like ~6% in average. For 140TH/s it would be normal too see 8,4 TH/s drop in one day. But next day it must go up, otherwise its not variance anymore. Now hashing power is going down two days in a row, looks like a lot of devices are being disconnected.

Can we trust this chart and believe that all ASICminer devices are included there?

For me it seems strange that at some day unknown user has added 40 TH/s to network, and then all this power suddenly goes down. At the same time, known ASICminer devices also go down. Its like both these device groups are related. Coincidence?

That's a hell of a drop. They said a reason why yet?

What's interesting is that this might mean ASICMINER has hashing power that it's not reporting to the shareholders.

Meaning it's REALLY mining with 40 THash/sec but only reporting and paying on 20. Food for thought.

Now ASICminer's problem look to be solved, and its possible to look at hash speed fall and raise during this time:

Red area - ASICminers average daily data from http://www.asicminercharts.com/
Green area - all other miners together. Both areas are stacked.
Blue line - ASICminers hash speed again, but not stacked, so its easier to see overall fall and raise.

On 13th ASICminer has achieved new personal record (36TH/s), and started to loose power after that date for next 6 days.
But, for other network devices - hash speed record was achieved on 12th, and next day there was 20 TH/s power drop (usual day fluctruation during that week, so nothing special).

ASICminer and other network devices had hashing power drop with 1 day difference, but further power fall/raise happened differently for them. I think there is nothing related between ASICminer and other device power fall, just coincedence.

But then there is new unresolved question - who was periodically adding and removing 20 TH/s from 01.06 to 12.06? Why they have stopped?

could it be Josh @bfl, trying to jerk us around?
