2013-09-12: Block id's 381 and 367 in the block statistics page are no longer listed as these blocks were not actually found at all. A pool bug due to double submission of successful blocks in certain circumstances is the cause of this. I've removed the blocks so they don't get paid and will manually adjust the DGM calculation this weekend so no user is affected by it. I'm tracking down the cause of the issue.

Still not solved... I'm not sure if you can recalculate DMG at this point...

Those are old blocks, latest block is #437, check:

Yes that is why I'm asking when recalculation will happen and if it is still possible... Since "will manually adjust the DGM calculation this weekend so no user is affected by it" was long time ago but we are still affected...

The strange hashrate difference is happening again.  Been monitoring it for about an hour.  I have low rejects and HW errors but pool is reporting hashrate to be about 15%-20% lower than actual.  I first saw this happening about a week ago.  Will this loss of hashrate affect round payout?

Could the pool operators perhaps shine some light on this?

Hello, i have a question...

Why in https://blockchain.info/es/blocks/Bitparking says that the pool have founded 3 blocks 03/11/2013

And

http://mmpool.bitparking.com/blockstats says that in the same day we just founded 1?

can someone explain it to me?.

Blockchain isn't always sure, it's very inaccurate

Thanks... but i tought that blockchain info gets his information through the blockchain, so it's different?

I'm kindda disapointed of blockchain.info

[bitpop]

No it guesses
Pools don't own blocks, blockchain guesses by ip
Don't be disappointed it's just a bonus metric

Is there a way to crowd source information, so the pools could add info to the blockchain.info system? 

That could create more misinformation than information (especially with plenty of people trying to not own btcs), but I wasn't sure if this functionality existed.

You can add public permanent massages in transactions

[bitpop]

Blocks are harder to correlate because they are virgin coins, no transactions
Blockchain looks the relay ip which should be the pool since they stay very peered but another pool could relay it to blockchain first
Ips can change
Blocks are as anonymous as you can get
There's no need to track them
A pool tagging them like p2pool does do can get them attacked and forked

Are there any statistics on how profitable mining at bitparking is? How much more income does merged mining deliver? Are we talking about 0.1%, 1% or 10%?

Calculate the nmc value and their ratio. The others are like 0%

It's been less than 1% recently; however, in the past, it's been as high as 3-5%.
