TheSeven just clarifyied something via irc from the last chat, which was already pasted
here (timestamp below is US/Central)
[09-21 12:27:20] let me quote sam (or whoever was using the skype account at that time): "they do but they will stop hashing after a few cycles and restart back" and "never showing the full hashing speed we have at any moment, i could show some mining address but that would not stop the FUD because of this"
[09-21 12:27:45] and I haven't talked to them since a week, they're somewhat hard to reach. so I'm not involved with rev1 yet.
[09-21 12:28:20] ok..
[09-21 12:28:21] note that these quotes are also a week old, they might have made a lot of progress since then
...
[09-21 12:50:53] sam explicitly confirmed that they were only restarting after several billion hashes
[09-21 12:50:59] okay
[09-21 12:51:05] several as in more then four?
[09-21 12:51:10] yes
[09-21 12:51:12] so more then a whole diff1 share
[09-21 12:51:21] he basically said "every couple of diff1 shares"
