I want to make it official too:

You guys are lucky. I have whole 6 Satoshi on that block

I confirm, round 19090 looks problematic.

If this is not changed, I will leave the pool - over 4 hours and nothing??? Next block 1 min shorter and normal ...

And this is not the only one  in the last days:

19080 (3:38) and 19068 (the nearly 12 hour block) I get only half of normal!

Round 19090 eh...mere coincidence that it is 06061 upside down?  hmm?

[bitdude]

Obviously, if some ppl do not get points on quick blocks, some other will do. This is, however, another unpleasant factor that you can hardly affect.

Umm... no offense bitdude, but if your hardware isn't submitting shares quickly enough in short rounds... maybe its your hardware.  Up until recently I was only running GPUs and the VAST majority of short blocks were well within the acceptable variability one should expect in a short round.  Short rounds are unpredictable. If your miner(s) happen to be working on a higher diff share(s) during the short round you may not submit those in time to get in the round.  Its the nature of mining.  If you've changed your diff on your workers, maybe consider lowering it. 
All in all, the scoring system has some flaws that usually get fixed by Slush, but for the most part it works.  If you don't like the variations in pay, thats ok, there are plenty of pools with very consistent pay (PPS or PPLNS).  But don't go bashing Slush's system just cause you don't like it. Feel free to share concerns or ask questions, but bashing a system you don't seem to understand or like is kind of pointless.

None taken

Well my setup is as recommended - i.e. I have picked up the expected hash rate, which I did deliver in fact and the difficulty was selected. Hence if the difficulty setting is a problem here then the recommendation is poor in the combination with the scoring system. I'm not really saying that Slush's system is useless, it just does not handle these situations fairly - in my opinion. The scoring system itself should not, in my opinion again, force people to submit large number of low difficulty shares instead of working normal. I really think the suggested difficulty is correct here and it is the flaw of the scoring system. I think the problem is that it starts from the scratch with every new round.

I do not really want to offend anyone here, just explaining why I left this pool - i.e. it might be the case that more people did not leave just because of poor luck ...

Fixed thank you slush

How is it possible to mine a bit more and be paid less?

Please explain slush! I don't see rounds under 0.08btc in my stats.

[STT]

I don't see rounds under 0.08btc in my stats.
 

Difficulty rose and others are hooking up asic which means anyone standing still appears to be going backwards, hence you recorded a new low payout.   BTC is a hard road seems to me, I only hope its worth it and the world uses it more; so price rises

And what are you talking about? I only ask about 2 similar pool rounds that happen to be one next to other.

[angryrob]

all that stuff has to do with the scoring method that Slush's pool uses. note that in the explanation you aren't rewarded based only on the number of shares contributed, but based on your score.

click on the "what is pooled mining?" on slush's site, and then click on "score-based reward system"

that leads you here: https://bitcointalk.org/index.php?topic=1976.msg50002#msg50002

the end result is that two seemingly identical rounds can have variance in their rewards, but over a 1-day and 7-day average all the variances average out.

the score based reward system is designed to be a deterrent to pool-hoppers. (i'm not saying you were pool hopping, i'm saying the variance you see is a result of this anti-pool-hopping system)

I think that this link has a pretty in-depth look at this whole process: http://organofcorti.blogspot.com/2012/09/43-slushs-score-method-and-miner.html

it's from 2012 tho so i dunno if all that information is still exactly 100% correct.

STT is also correct: if the hashrate of Slush's network rose between the two rounds, but your hashrate remains constant, then you will notice an increased variance between those two rounds. you end up with a smaller piece of the pie, because relative to the entire pool, you contributed slightly less. this goes back to the SCORING system: you are rewarded for your score relative to the rest of the pool, you arn't rewarded per share. obviously more shares = more score, so in a very basic sense you are rewarded per share, but as the links above describe, it's more complicated than that.

...

I know all about it, and the scoring system too. I was poolhopping 2 years ago but not the case here. The scoring method is designed to reward miners that stay until the block is found and pay only the last half of the shares used to find the block, basically inverse prop. payout. When organof started writing I was experiencing with it imo.

As you probably can see I submitted more shares in the second round even though it lasted only 10 minutes more. My miner didn't disconnect from pool or anything, shares prove that. Btw, I hate the scoring system like everyone else because it penalizes miners for every possible failure, but what we're going to do if poolohoppers are far more dangerous yeah. I will hate Meni Rosenfeld for this one my whole life.
