Being new to this, I watch it like a hawk. I had no connection issues, and was submitting shares all the way to the end. I saw the estimated reward drop drastically a little while before the end, but didn't worry (happened before and Slush sorted it).

my reward 0.00000010 - something must have been wrong with the calculation (which is what was the problem on previous occurrences).

I am starting to think it will not be sorted this time...

Considering wtih just 2 cards going that I've had lately I've been getting .00029ish I think that's a bit high.  I'd be happy to danate mine back to the pool if slush needs to make a correction.

[ewitte]

I'm going ot be honest I think I got paid too much on the block that you guys are all talking about unless I did indeed earn what I did because a bunch of other shares didn't make it in mine seems to be a bit high.  help us Obiwan (slush).

Regarding that block #17925 I suspect what's the problem .

From what I can see it appears that majority of the folks didn't submit any shares in the last X minutes while others did continue to submit shares.

The most reasonable explanation to this is that there was some network issue (routing or clogged traffic) and something happened to **some** of the pool's endpoints but not to **all** of them.

In other words - a few of the IPs listed below may have been DDoS-ed, and those that were connected to them suffered as they were unable to submit their shares, while the unaffected IPs worked just fine and those people connected to them did get their (at that point) fair share:

that's from a few days ago:

C:\Users\me>nslookup stratum.bitcoin.cz
Server:  rdns-lb-01.orange.rr.com
Address:  66.75.160.63

Non-authoritative answer:
Name:    stratum.bitcoin.cz
Addresses:  54.225.117.74
          54.215.3.100
          54.215.3.101

          54.215.3.103
          54.225.68.97
          54.225.116.40
          54.225.116.174
          54.225.116.221

and looking at my currently connected worker - I am currently connected to one of those:
TCP   192.168.0.70:54312   54.215.3.103:3333   ESTABLISHED   


Unfortunately I don't think slush would have any (easy) means to find out which IPs of the pool worked at that time and which didn't. If that's the case then I guess all I have to say to the winning folks - congrats for the bonus!

(that's unless slush wishes to manually recalculate the payout for that block, but the time for this is running out rather quickly too)

Thats totally not the case! The submitted shares figure from most people is correct.

So the number of my shares for that round was about right - just 2% over average (that's in seconds/share or how many seconds it takes me to submit one share).

I wonder if there was something wrong with the timestamps of those shares (as recorded by the server). The result is almost the same as if I didn't submit any shares during the last 5 minutes, and what could be a coincidence - the round ended at 16:05:44 (e.g. 5min after 4pm). I'd be curious to find out if due to some glitch (time zone adjustment?) those shares got timestamped with +/- 1hr.

Why is everyone only looking at the number of shares they submitted to a particular round and deciding they got screwed? Not all shares are equal - you have to divide your score by the total score for the round to determine your reward, as Slush clearly points out here: https://bitcointalk.org/index.php?topic=1976.msg50002#msg50002

Code:

reward = user score / total score * 25

The scores for round 17925 probably got reset (normalized) right before it ended, resulting in many people with very low scores and only the few that managed to squeeze in a share or two right at the very end getting most of the reward.

There's been quite a lot of talk about the reset being busted before.  Seems to me dividing by a factor would be fairer (and still prevent overflow).

that system is old...On the website it is:

This 25 BTC is divided among all of the users that contributed to that round, weighted by the number of shares that they earned. Therefore, the reward earned by a given user is given by the following formula:

(25 BTC + block fees - 2% fee) * (shares found by user's workers) / (total shares in current round)

which is what is being used now

[visdude]

Slush, can you please look into the following?  The reward is unusually very low and it never corrected itself; the blocks before and after this are pretty normal:

That's not right. If you do the math on any of your rounds in the statistic page you'll see it doesn't match your formula. And in fact, right beneath the paragraph on the website that describes the formula you posted, he says "In fact the formula above is simplified. The real math behind the payout system is described here" and points to the same forum post I linked to.

If you bothered reading any of the posts you will see that they're not.
Using the correct calculations peoples scores are off by a degree of an extra 0.0000 ... thats more than the normal "shares near the block discovery are worth more" debate.

Actually, I did read the posts. Like this one:

https://i.imgur.com/VElQt3V.png

Seems to be an issue here.  From my calculations, 1784 / 11634278 * 25.21733124 = 0.003866825163724, not .00000048

What's the deal?

wow one day of mining in one block ^^
I'll have to say goodbye to them soon i guess...

should have got 0.98*(1325/11634278)*25.21733124 ~0,0028719413351649 (this valid only because i did not stop any of my miner so good approx)

They're all calculating rewards from shares, not scores (weighted shares).

And then there was this:

Many of us face the same situation with this block. This has happen quite a few times, most of the cases when the score reset is immediately before / very close to the end of the round.

And as a corollary:

I'm going ot be honest I think I got paid too much on the block that you guys are all talking about unless I did indeed earn what I did because a bunch of other shares didn't make it in mine seems to be a bit high.  help us Obiwan (slush).

The pool got a lot more horse power lately - last week it was around 8-8.5TH, over the last day it's been around 9.5. That's roughly 10% more people getting paid, thus everyone roughly making 10% less per block. On the good side we make more blocks per day which should more than compensate.

Guys and gals - let's stop complaining about that 17925 block. It's more than abundantly clear that something went wrong (or at least doesn't meet our expectations).

For good or bad - Slush is the only one that can tell what exactly happened and fix it.

And after all - for majority of us the lost amount is rather insignificant - the daily income would be affected by a single-digit percentage. So - let's stop whining about it.

Slush hasn't posted for over a week, so he might be on vacation and therefore won't be able to fix it. If that's the case - we'll have to live with it.
