I keep seeing a lot of people that I think are confused how pooled mining works.
We aren't all doing part of a big problem, and a round is not just one block. Every time the network finds a block the problem changes cause they are all a chain. A share isn't a piece of a puzzle it's a lottery ticket. And we are all pooling our lottery tickets in hope one of us wins with the agreement we all split the proceeds. So this %CDF isn't coverage of a problem space it's just a probability that a winning lottery ticket will be made for the latest link of the chain.
The real trick is that we are all working on low difficulty attempts so we can make lots of them in the hopes that by chance we'll hit one that is above the required difficulty.
Or at least this is what I'm pretty sure is the case usual disclaimer applies I'm not an expert.

Hi I have a question regarding difference between this pool and bitminter.  I was a big fan of this pool but with the DDOS attack it seems like I've been getting less reward at slush since then.  I have about 300 mhash/s and the way I have to do it is I run it only at night, overnight, so it's like 12-13 hours a day of mining (plus weekends all day).  Bitminter and slush use different scoring systems.  Does anyone know which pool I'm better off at based on my mining times?  Thanks for the advice.  

This has been addressed in the thread already.  The difficulty changed right around that same time.  When the difficulty gets harder, your rewards get smaller.

Didn't notice however a new card came online the same day and another 1.5 yesterday/today (returned a lesser card).  I was at about 850MH/s during the DDOS attack now approaching 2GH/s.

in most distributed net processes a big problem 5+5(3-5)x5(19/72+4)  is parceled out to systems
so   bob gets 5+5
joe works on (3-5)
and so on then its put back together

least thats more or less how it works with rccrypt

I understand difficulty changed, I was more interested in the answer to my main question.  Is slush or bitminter's scoring system better for someone who can only mine 13 hours/day.  Thanks.

I'm not an expert on the btc protocol per se, but I do understand the mathematics involved, and this is a very good and succinct description for lay people. However, the %CDF is not really a probability, but a measure of how many blocks of this difficulty one would "normally" expect to have been found after this many lottery tickets (shares) have been cast.

EDIT - odd as it may seem, the actually probability that share N finds the block is exactly the same as the probability that share 1 will find it.

Difficulty does look higher to me about 20% at least.

Nope, difficulty has been unchanged at 10076292 for a while now - http://blockchain.info/q/getdifficulty - I've got a ticker monitoring it. Just an unlucky round - you get them - be philosophical about it - take the good rounds with the bad and all that...

Don't think the hours per day you can mine make any difference all.  Your best bet is to try both and figure out for yourself which one is best.  Everyone's setup is different, and will have different results.

I remember it starting with an 8 but don't check that frequently

Probably shouldn't comment since I haven't had a chance to read those yet, but I did mention above about how I thought the system was outdated.
Judging by the hash rates in the top of those they aren't very recent.
If im wrong, please dont hang me! I'll apologise for my ignorance once I have had time to look at things properly.

4.2 and 4.3 are the important ones - 4.1 is just background. They are from last year, but the score method is the same now as it was then.

Very good read indeed. I wonder how many of the forum members will take the time to read & understand (!) it. I see a rather wide spectrum of skills and attitude and many reoccurring questions that makes me assume the majority will just skip anything longer than a few paragraphs. Anyway, congratulations, I really recognize the full worth of these quality articles.

Cheers,
   T


It would be great if people actually *read these docs*  rather than questioning the scoring system - there are other pools...

Jcw188 (sorry quoting just doesn't work here): Bitminter is probably best for you as it seems to have a pure PPLNS system while the algorithm Slush uses favours shares submitted just before a block is found. To get well paid you'd need to stay online for a long time or log off just when a block is found.

Q: "What is worse, ignorance or apathy?"
A: "Who knows? Who cares?"

:-D

On a serious note though, given the recent attacks I prefer to be alert to _all_ anomalies.

I assume you are wondering why there are two values for a given day - even though you don't make that clear at all...

You are looking at two functions plotted on same graph - a 7 day moving average and the actual data point for the day...

What he's saying is that it went from april 29th to may 30th, when it should have gone from april 29th to april 30th.

And I'm guessing that the reword is also off since it is probably pool earnings...

I can only say I see no problem with my graf

yeah, now that I actually look at the graph, I'm not seeing the same problem.  The dates are all correct for me...

Well not really... Slush method is beater since you get more if you are not stooping the miner. And you say it is running 12 hours or more... And if you turn in on at the end of the run you get about the same as you would if it was running all the time... So you loose a lot if you go of at the end but you get also a lot if you came at the and. So it evens out. As long as you are not making stops all the time... And since Slush method is beater at protecting against hoppers you get more... But you get a bigger variances. So you might have a good and bed days...
