Nine hour block!!! Ughh!

Rookie question:
I have 9 of the Block Erupter USB sticks hashing all on the same rig, which averages about 3 Gh/s. Should I set the difficulty for the worker to 2, since the total hashing power is over 2 Gh/s, or should I keep it at one, since each stick only has 335 Mh/s of power?

Keep at 1, else endless discarded.
?
I've always believed that the rig should behave like one worker with combined power. Is there any reason for discarded shares other than bad configuration/setting?
Interesting note: I have accounts on BTC Guild and Bitminter as well. If I point my nine Erupters to either of their pools, with a worker set to a difficulty of 1, both pools auto adjust the difficulty up to 2.
I might have to do a little experimenting, and compare 24 hour totals.

but this -=> 31334.034 Ghash/s hurts too! hah
I am glad i don't get hurt by stable payout curves at all.

I think, the comlete last Reward-Calculations are not correctly.
normaly it was between 0,08 and 0,1 per block and now it´s only 0,05 and 0,06.
Think should be stop Mining at Slush. At #19437 i got only 0.00000192 by 27750 shares.

I see the pool is pushing close to 30,000 GH/s and the difficulty went up today to 37392766... I keep adding miners but just can not keep up ..
yeah each diff negates 660mh/s!

19436, 19437, and 19438 all just over half reward for me... and that is half with regards to our new increase in hashing power.(another 3+ TH/s! nice!) Wondering if it's cause of the increase hashing power that blocks need to be recalc'd more often. or maybe i just don't notice it so much sometimes as I do right now.
I agree they do seem a bit off but the luck has been nice.
The rewards are lower because pool hashrate increased so much tonight: 32 TH !!

I'm still seeing a reduced reward for 19421 (249905). I was actively watching it and about 1-2 hours before the block was solved, I saw my estimated reward drop from 0.003xxxx to 0. Then it slowly built up little by little, to 0.0015xxxx, bur never recovered. This really sucks because the round lasted over 7 hours.
Unfortunately, I've decided to stop mining there for the time being until the issue can be confirmed as fixed.

I just checked mine and with 2 confirms left, block 19421 is now showing a normal reward.
yep. fixed now.

Hi thanks I am using 3 hubs and one of them is plugged into the raspberri pi itself I am guessing this one is the problem. I have a fan on all of them.. I will be buying a better hub however. I have wasted a lot of money on hubs so far
So which hubs are you using? Running 4 on each? What is the volts and amp on the power adaptors?

I take it you have USB Eruptors? what kind of hub are you using? Port 9 is way off...if the power supply is right and cooling I only see less than 1% error on mine. So all yours seem to have a high error rate and like I said port 9 is way off.
I also hope #19421 gets fixed.

Website is under the maintenance, but mining works without an interruption. You can follow updates on Facebook page.
I'm not on fb and won't be.
I'd prefer another place for such announcements, some "normal" pages like here on bitcointalk e.g.
(BTW, I can't see any (public) announcement on this event on the ffb.)

I do not think it is very difficult. The value of each share you submit is calculated with the following formula:
scoreshare = exp(t/C)
where t is round duration in seconds, and C is a constant, currently 200. This means the value of each share is exponentially growing, so old share have significantly lower value compared to recent shares. So if you stop mining while others don't, your part of total pool score for that round will decrease exponentially. You can read the original post about this reward calculation method here: https://bitcointalksearch.org/topic/m.50002.
Additionally, based on measurement I have found that each hour, t is reset to zero and your score is divided by exp(3600/C). This is probably to prevent an arithmetic overflow (see http://en.wikipedia.org/wiki/Arithmetic_overflow).
Hope this helps,

(Also the whole pool's score is reduced by the same factor, not only yours.) :-)
[edit] (In fact, it's the pool's score that is the candidate for arithmetic overflow, not the your one...) [/edit]
Thank you very much for posting the constants that resulted from your research, Tibor!

hmmm 19425 fixed and normal for me now.
wonder what is up with 19421. I'd almost say it was just my own bad luck (variance) but so many other people also posted about it. oh well, i'm not ganna sweat about 1 round being a bit low.
19419 was invalid tho? just noticed this. super bummer. i had a pretty nice reward on that one too lol
I confirm, 19421 is wrong. wonder what is up with 19421. I'd almost say it was just my own bad luck (variance) but so many other people also posted about it. oh well, i'm not ganna sweat about 1 round being a bit low.
