On the http://mining.bitcoin.cz/stats/ Page
For the current block was the:
Total score of current round: 10645738685290.2051

and now alfter 5 min is 1726123.6787

The variable has flipped?

Something went crazy for me overnight (PST), reported hash rate is still the same but all rewards halved.  Switching to stratum2 from stratum3.



so you changed your miner from pointing from
Name:    stratum2.bitcoin.cz
Addresses:  54.215.3.101
          95.211.52.40
          54.225.117.74

to
Name:    stratum3.bitcoin.cz
Addresses:  54.215.3.101
          95.211.52.40
          54.225.117.74

maybe u should try next
Name:    stratum.bitcoin.cz
Addresses:  95.211.52.40
          54.215.3.101
          54.225.117.74

in other words u changed a name to another name that all point to the same ip's, in your mind u did something when technically nothing was done.

interesting to note Slush knocked off 3+ ip's

Score resets to zero top of every hour for everyone, but shares are not reset -- you don't lose anything.  Score has to reset because on long blocks, the number could get big enough to overflow the registers and peeps would start asking about why they were seeing negative scores Smiley

iFA88, yes youre test case is valid if no-one hops the pool....
BUT, lets say theres pool B with exactly the same hashrate ---->

#1 Block Duration: 1:00:00 CDF: 30%
Total Shares: 10'000'000 My shares: 500
My estimated reward: 0.00125BTC

#2 I hop to pool B at this time with 500 shares.
->

#3, pool A Block Duration: 2:00:00 CDF: 60%
Total Shares: 20'000'000 My shares: 500
My estimated reward: 0.000625BTC

#3, pool B Block Duration: 1:00:00 CDF: 30%
Total Shares: 10'000'000 My shares: 500
My estimated reward: 0.00125BTC

== Total estimated reward from 2hours = 0.000625BTC + 0.00125BTC = 0,1875BTC.
(vs. mining only with pool A, without disconnects, which case reward is still 0.00125BTC)
and you must understand that if someone gets more than he should its less BTC for the rest.
nb. This example is very simplified

That is completely understandable, but I think it's not balanced or well designed if 10 minutes downtime due to connection problem causes 50+% loss on the actual rewards.  :O

I agree its kinda harsh, I guess slush's variables arent ment for hashing speeds of today.

0.000625BTC + 0.00125BTC = 0,001875 ^^
But its very important, when the block is founded. I think i dont recvive more BTC with these method^^

Yeah, it doesn't seem fair -- had more than a few of them myself -- but how can the server tell if you're having a connection problem or if you've hopped?  How long does it take for the average mining operation to notice and correct a dc, and how could you account for changes in the chain?  Taking your case as an example, ten minutes is the average block time, so most likely a new block would start before reconnection, maybe even a new round -- where would you want to apply the shares you've started generating again -- the previous round or the current round?

U mean that on 59:59 time i have 500000 score and the total score is 400billion, and after 1:00:00 i would have 0 score and the total score would are 0?
Then why can calculate from this?
U work me for 100$/h job, but every hour i reset your work time to 0min Cheesy and the end of day i pay you out with cents?Smiley

I know why are flip. But when resets then why can from this number calculating?
I mean, then on 59:59 is 400'000'000'000 total score, and then over 1:00:00 is 0 total score.
The slush method says:
reward = user score / total score * 50
Then every hour have more participations?Smiley
I have now 53413,5817 score from my workers.
Current total score is: 4031371780,6554
/*
Current round duration:   2:25:39
Current shares CDF:   86.79 %
Current Bitcoin block, difficulty:   238884, 12153411
*/
so my reward is now: 0,00066247402380 ?! (528 shares, total share is now 24596507)
And alfter a hour we see this method so:
my reward = 53413,5817 / 0 * 50 ?
I dont understand this, i think there is a math bug^^


No math bug -- your score is increasing at the same rate as before because your hash rate is the same.  The total pool score is increasing by the total pool hash rate (and that can change as miners come and go during the round).  Not sure if you've seen this, but the latest audit for Slush's pool has this about the scoring system: http://organofcorti.blogspot.com/2012/08/42-slushs-score-method-and-miner.html?q=slush%27s+pool

I had the same issue today with one of my machines running guiminer.  I had to flush my dns and it started working again with the standard slush setting in guiminer.

in case you don't know:
ipconfig /flushdns

In windows vista or 7 you want to open the cmd as administrator.

EDIT: and just to be clear, I'm not using Other for my server, I'm actually using the slush server option.

It seems to me that how higher the pool's hashrate, the longer the blocks. But that can't be correct, isn't it?

He means the countermeasure of counting shares in last blocks (hence overstriked)
You can test it with setting up a pool with out hop protection Wink ill be happy to be with youre pool until first block hits 43%, ofc Ill come back after you find a block.
Theres nothing wrong in the math.

Its important only if you're sample is 1-10 blocks, but if you mine thousand of blocks pool hoppers gain extra ~30% Its statistically inevitable.

If pool hopping wouldnt be an issue, why would pool operators run complex algorithms for the payout. There actually were pools with payout you mentioned, altho theyre all dead or went to complex payouts.

NB. pure PPS payout (like 50btc) is based on pool operator taking the risk. individual miners dont gain/lose if the pool finds 1 block or 100 blocks per day.

Are the stratum servers down?  Several people in the chat room (myself included) can no longer reconnect.  I also tried flushing my DNS tables too.

Getwork fails too.
