Ever since an all-night wifi outage, I'm getting frequently underpaid. When calculating the expected btc before my wifi outage, I was getting consistently more than expected. I guess this is a nice example of how the slush points work.

                                                                                         my btc                                  my expected btc      
19289   2013-07-25 14:25:20   3:10:10   65087874   8914   0.00267229   25*8914/   65087874  = 0.0034
19288   2013-07-25 11:15:10   1:06:44   22496665   3072   0.00314420   25*3072/   22496665  = 0.0034
19287   2013-07-25 10:08:26   0:05:58   2027467   308   0.00380032   25*308/   2027467    = 0.0038
19286   2013-07-25 10:02:28   0:01:30   497916   70   0.00342332   25*70 /497916           = 0.0035
19285   2013-07-25 10:00:58   2:29:49   50785547   4448   0.00315257   25*4448/50785547     = 0.0022

(The last one is higher than expected as I switched on my miners half way through that round)


My question is, how long does it take to get back on to better than expected btc? Cheers


This is also affected by increases in our Hashrate. If our hashrate goes up your return will go down. But, it should be offset by increasing the number of blocks we find. You really can't tell much looking at each individual block, your graph 7 day average is a better indicater.

OK, so you're saying it was a coincidence that this hashrate increase, at the apex of my going from >expected to <expected happened while my miners were having a nap. I wonder what the odds are.

How does the hashrate relate to the shares per block being different? I can't see how that works.

If the pool hash rate stays the same while the network hash rate increases, the pool's chance of finding a block decreases, i.e., it will take longer on average for the pool to find a block.  Similarly, if the pool hash rate is increasing while the network hash rate stays the same, the pool's chance of finding a block increases, resulting in shorter round times.

Now, if your hash rate stays the same while the pool's hash rate increases, your share of the pot decreases because your payout is based in part on your_shares_submitted_during_round divided by pool_shares_submitted_during_round.  Your lower payout will be offset a bit if the pool has an increasing hash rate because the pool will find on average, more blocks.

I understand that  your_shares_submitted_during_round / pool_shares_submitted_during_round     is what is affected by respective varying hashrates. As such, an increase in the pool's total hashrate explains why I would get a smaller proportion of the total shares for a block. I know that here is added variance to do with how close your last share in the block is to the end of the block, which would explain why the shares proportion doesn't translate perfectly to my earnt BTC as with a proportional earning pool. What I didn't get was why my earnings might have been more than expected more often than less than expected, until I stopped mining for 8 hours, then started again, with more 'balanced' expected earnings.

To be sure, I plotted the numbers for before and after the outage, though not really enough points to confirm anything. I'm guessing that I was just having a lucky run before the outage. If that's right, then there's no long-term penalty for disconnecting other than the current round. Is that right?

i just noticed that it broke thru 25 TH/s

that is the highest i've ever seen the 30-minute average for slush ^_^

gg

It is cuz I added another GPU Miner... I do that and someone adds like 200 Jalapenos!

I feel that way everytime i add a ASICminer stick.  Undecided

I was going to buy 4 ASICminer stick yesterday... but first I went to the calculator to see much my monthly BTC would increase.... then I increased the diff from 31256960 to 36256960 and noted it negated 2 ASICminer stick, so every 10 days 660mh/s gets negated... So I decided maybe I should stop chasing the diff. the Video cards I can sell at a profit, ASICminer stick will be useless soon. well to most people! people with 50+ already will love every single one tossed out heh

That's what I'm waiting for.  It won't be long before you can get them for $100 or less...

you can buy them for less than $100 now on Amazon now. i was thinking more like 1-5 USD.

Um, from what I can see, only if you buy 30 of them...lol

Or link please.  Bitmit has some close to $100, but nothing that I would trust has hit that mark yet.  $1-$5 is a long way off, at least in my mind.  Maybe a couple years down the road, when asic innovation has sped up more...

Hello, I'm newbie here. I just tried this pool yesterday and already produced about 13-15 shares (I don't remember exactly) and then I turn off my miner and go to bed. This morning I saw my estimated reward become zero and nothing at my unconfirmed/confirmed, so what I've mined yesterday is totally useless?

Thanks.

Yes, saddly, this is not a pool for part time miners. you might want to try btcguild.

This pool doesnt use Pay Per Share as a reward system, it uses a different system which is a bit difficult to explain as I dont completely understand it, but your reward will quickly drop to zero if you quit mining... This is to combat pool hopping. Leave your miner on through the end of round until a block is found, and you will be paid your reward for that block. Other pools have PPS as options, but the fee is always higher because of pool hoppers... Happy Mining!

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://bitcointalk.org/index.php?topic=1976.msg50002#msg50002.

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,
   T

you can buy them for less than $100 now on Amazon now. i was thinking more like 1-5 USD.

Um, from what I can see, only if you buy 30 of them...lol

Or link please.  Bitmit has some close to $100, but nothing that I would trust has hit that mark yet.  

Well ya could yesterday, there were some for $92.95 + $4.75 shipping, but they are gone now.  Tongue

Group buy for K1 Nanos: ~$55 per USB miner:
