Thank you Dr Haribo for the link but there are only couple posts discussing the merits of pools .
What I was referring to was that even though BTC Guild has the most Blocks discovered does not instantly mean it is the preferred choice for a small new miner .
No, the Q&A I linked to is about the assumption that "since i have a small hashpower I must join a certain type of pool." I posted that question on the Bitcoin stackexchange because new miners make that assumption all the time.
Forget the small vs big miner.
My findings suggest that,
Slush's pool over the 100 blocks found took 580 ghs of power per block .
While:
BTC pool over the 465 blocks found took 619 ghs of power per block.
So over the last few lottery rounds,
BTCGuild won once with 619 lottery tickets, and Slush's pool won once with only 580 lottery tickets. You can take that to mean that Slush is better than Eleuthria at playing the lottery. What I am telling you is that thinking so is wrrong, the real explanation is that lotteries are random.
Not sure lottery is a fair comparison since not many if any win twice even in pools of 1000's of factory workers .
But yet 13 pools averaging 637 lottery tickets have in a one week won our bitcoin lottery 1322 times.
This is far from a lottery this is the result of a complex mathematical algorithm controlled to results in a payout every 10 minutes ,a lottery can go for long periods of time and on most occasions resulting in one payment to one individual.
Considering these facts what has bitcoin mining got in common with a lottery apart from who in a short period of time will be allocated the winning ticket ?
I wish the lottery had a mechanism to regulate the payout to once every 10 minutes perhaps I would not be here lol.
