gpudude, I'm definitely missing some payouts here... I've been mining consistently for about 7 hours. My address shows up in the payouts, but I'm not getting paid on quite a large number of blocks.

For example, there was a block found at 20:50, and two at 20:58, and i did not receive any payout for these despite being in the payout list. This is just a very small example of the blocks I haven't gotten paid on.

In addition, I have horrible efficiency on your pool right now. 63% on my 900kh machine. I am using stratum, and I'm using your recommended settings (for queue and expiry, as well as the +#.### for share difficulty)

My address is WkBoLrmemSoLr3vGo9J9ptYPKXgfMvGS4o

Please look into this. I'm switching to a different pool until I get some feedback on this.

EDIT: Totally panicking here because you didn't respond right away at 4am. (just in case, I was being sarcastic).

Hi MikeyNick,

I've had a look at my miners which are pointed at the pool and for those times you are talking about I have been paid out (and constantly afterward). I am not sure what the reason is for you not being paid. For my miners I have removed the expiry and queue settings as they were needed in the coins early days when difficulty was low.

My miners also do not have the difficulty setting - I recall DMaster2008 stating:

To get paid, you have to send a share which is more difficult than (Share difficulty) * 65536 (and this share should be accepted).
You can see "Share difficulty" value on http://212.48.67.50:8336/static/ , now it is 0.395 (it depends on the p2pool's hashrate and constantly recalculated).
So the share should be more difficult than 0.395 * 65536 = 25887 (like "Diff 25.9K/..." in cgminer; the first part of such "difficulty" is always more than the second one, which is managed by "+0.0000xxxx").
Note: If the first part of your share difficulty is more than the network difficulty, you will find a block.

You can see such lines in your cgminer console:

"Accepted Diff / GPU pool "
or
"Rejected Diff / GPU pool "

"Diff:183K" is the network difficulty.

It's rather hard to produce such a share even with Radeon HD6950 at 448 kH/s.
I had to set the difficulty modificator (after my WDC address) to "+0.00196000", it provides "the second part of share difficulty" = 128 and "the first part of share difficulty" at least 128.
It allows to produce shares like 30K/128 (and higher) nearly once per hour. One such a difficult share is enough to get several payments. The more such shares you produce, the greater your payments are. People having rigs of several HD7950/7970 can produce more shares and more chances for them to be so difficult

Also the fluctuation of this pool hash rate and network hash rate means that share difficulty is fluctuating from 0.139 to .045 - so another thing to check if you are using the share difficulty tweak is what DMaster2008 mentioned above. To save constant updating, I personally for my 8MH/s have removed the share difficulty at the end of the address, and the expiry & queue values.

As of right now, payouts are working - they are just slower for two reasons 1) Low pool hashrate 2) low pool hashrate versus other pools vs network.

My recommendations are;
Remove Difficulty "optimisation" (or calculate it so that the shares you are submitting are sufficient enough as DMaster2008 mentions above) & remove queue and expiry settings.

Thanks
