That's my opinion. Running your own node is usually fun.
Unfortunately, the setup is not trivial, so I made my node public to support the P2pool idea.
LOL?
Download zip, unpack, run. Node setup done.
[ironically]
so easy?  Wink
I must install python, twistet, Set Bitcoind as server and so on. 
whats with people who use a pool and an e-wallet, which never used a Bitcoind ?

why are there still so many old nodes, when ist easy?

Nicely done, but there is NO explanation WHY it is 10% longer than it "should" Tongue

Very nice and thorough analysis... am impressed.

Small donation from a small miner, sent.

Will be interesting to see, if you do this again for p2pool, how forrestv's recent changes to increase propagation of found block info, affects the data. Given enough time of course. Smiley

I'm keen to revisit this in another 500 blocks. Hopefully that will be sooner rather than later. I hope the hashrate ups a little bit.

I have a idea, but unsure how to prove it.
In my case P2pool.info ALWAYS and sometimes even my local node shows more hash rate than I have on my miner.
Maybe it it all ok in pool itself, just numbers send/taken to analysis are screwd? By this magic 10% ?

hashrate by p2pool on your PC and on p2pool.info is a GUESS based on the shares submitted at that time. I've had it say I've got 40gh/s because I mined with 1500 diff shares and got 5-10 shares in quick succession.

Maybe this "guessing" is the troublemaker. Some missed comma in code or something and all calculations can be trashed.
IE it is calculating that diff 600 share need 270MH (numbers form the roof) but in fact it need only 250. This way pool "guessing" that pool HR is higher than it really is, so time to solve block is shorter. But in fact it takes longer because real HR is lower.
In "normal" pools where SD=1 error margin is much lower (higher accuracy), we have SD~600 and rounding numbers up/down can make statistic troubles.

Edit:
From my week graph:
Local rate = 132MH/s
Local rate reflected in shares = 164MH/s
So pool "guessing" that I have 20% more hash power than I really have.
If everyone have +10% on stats then "bad luck" problem is only a statistic myth. If more ppl have over +10% ... then everyone should mine there Tongue

Thanks for your help guys, sorry to waste your time, i had the wrong password in Guiminer i am not sure how it happened as it was working before i upgraded, it all seemed to work with the wrong one, i could not see any errors, but the difference i can see is that on guiminer i now am showing a number outside brackets, so i am now getting 98 (50) where as before with the wrong password i was only ever getting an incrementing number inside the brackets with the outside number 0
ie 0 (50)

Thanks
Peter

I'm the noob here  Grin you tell me, i am just saying i found out why it was not working, without the correct password in Guiminer it was not allowing bitcoin to work with Guiminer and i was not getting credited for P2pool.
With my wallet password in Guiminer password field it works.

Theoretically, possible.
But at the end of the day, miners don't care about numbers, rates, stats and graphs. They simply look into their wallet and compare the daily income to other pools and to mining calculators. It is there where 10% are missing (it seems).

That's why I'd like some long term p2Pool miners to post their personal stats somewhere. Does p2Pool record your average round hashrate from which your earnings come, along with the earnings?

With my wallet password in Guiminer password field it works.

Maybe your wallet password is the same as your bitcoind connect password written in the conf?
If so, change your pasword! Too easy to steal your bitcoin in that setup.

Miner don't need any connection to any wallet.
Guiminer has only one spot for a password, which is for connecting to bitcoind/p2pool/pool. p2pool doesn't need and have a connection password, though?

yes and i had the wrong password in the password field in guiminer.

this stopped me mining via P2Pool.My stats stopped on P2Pool it looked like i was mining but i was not getting credits arriving in my wallet, now i have changed it to the correct wallet password i am now seeing stats and credits in my wallet.
