Is anyone else seeing some strange data in the estimated reward and their current scores? I have a current score of around 6000 with over 8700 shares and my estimated reward is about 2% of what I normally see for the same number of shares. My hashrate appears normal.

Any ideas or explanations?
With a very modest hashrate (about 7.5 GH/s split evenly between Slush and BTCguild) I see large variations in Slush.  This seems to be due in no small part to over-aggressiveness on the part of Vardiff:  it appears to go in cycles over about 20-30 minutes, dropping from difficulty 4 to 1, then up to 2, then up to 3 or 4, then back down to 1, resulting in big swings in the estimated reward.  BTCguild, meanwhile, remains steady on the minimum of 2.  Sod's Law decrees that Slush will often solve a block just when the estimated reward is at its low point, resulting in variance of over 50% even on reasonably long rounds when one would expect some consistency.

It seems to me that Vardiff is too sensitive to sort-term changes; while this may be a useful attribute in the first few minutes after establishing a connection, it becomes a liability once the worker has settled down.

Maybe vardiff needs to tone itself down after N shares or X minutes of runtime?

I have a question that is probably already answered somewhere, but, I haven't been able to find the answer.

The "MH/s" shown on the "My Account" page, for each worker.  Over what time period is that?  I assume it's an average over some time period, but, what is the time period?

Thanks....

current round

It's not true. Column name is "Mhash/s*". And below that is "* Average hash rate in last 60 minutes. Calculated each 5 minutes.". I really think that this means, that it's not calculated over whole current round Smiley

You're right.  I see that.  However, the current round has been running for 16.5 hours.  I brought one of my workers back online about 11 hours ago.  And, the Mhash/s reported for that worker is somewhere around 85% of what my worker is reporting.  And, in the past, this same worker has shown a hash rate on the pool of the same as it's reporting.

I won't be able to tell for sure until the block finishes and the next round starts, but imperial evidence suggests that the reported is _not_ a 60-minute average.  I'll keep an eye on it, but.

Bear in mind that Slush does not have direct access to your miner's hash rate, but has to derive it from back-calculation based on the work performed.  Your quoted variance of 15% is not something I would personally worry about.

And I believe you probably meant "empirical evidence".  Wink

Just a glitch. Happens from time to time. If you think its your vardiff then run a proxy.

I know they're not going to be the same, but I hadn't usually seen so much as 15% variance.  Again, I'm not too worried about it, and I'll know more only after the block is solved.

And I believe you probably meant "empirical evidence".  Wink

Quite right.  Thank you very much.  I'm always happy to be reminded when I get grammar/wording/spelling wrong.  I need to continue to improve if I want to have the ability to correct others.  ;-)

Noticed this too.  Such hiccups occurred some weeks ago and were always fixed eventually.  Raised a ticked with Slush support, just in case they are not paying attention.

I am observing something similar. Confirmed on the status screen showing unconfirmed on the account screen. As stated; historically slush sorts itself out.

Slush Block #22025 that was "processing...." on the stats page got fixed, but the confirmed blocks did not flow to the confirmed reward, so payouts were missed in the last cycle.  I hope this gets fixed soon.

Pool seems to have grown considerably recently. I wonder if there's an impression that some previous bad luck will equate to good luck. 97% over the previous 30 days doesn't seem totally awful but there have been some days.... Glad to see the growth.

Hi guys,

I need your help in relation to BitBargain's sellers test. There is one question that i am struggling with so i would appreciate your help very much. The question is:
"You want to sell at Bitstamp Ask + 4%, but never below 200 GBP per BTC. What is the price formula for this?".

I hope someone here is a BitBargain seller and came across this question on the test Smiley

Many thanks in advance and i am looking forward to your replies.

I'm running a total of 6 antminers (s1/s2) under bfgminer. The miners have been running stable for over 96 hours now. The software is reporting over 12Ghs in the 5 sec decaying stat. while the pool is showing just under 8 Ghs. That's an apparent 30+% under run and it been like that for over two days. Very low reject rate (under.5%) and NO hardware errors.

Any ideas and can someone give me the link to Slush's support page?

Thanks

Hello

Yes a few people see that it goes up and down..  mine sometimes shows 1.4TH/s  and other times 999GH/s  it seems to settle down and even out. Latest payout was awful compared to usual though  Angry

If you want to raise a ticket go to http://support.bitcoin.cz/Tickets/Submit

Happy Mining.

Mine was very low too (about a third of the preceding round).  Somebody ate all the pies, and I know it wasn't me.
