That’s right, over the past few days, btcguild.com payout has been a lot better than ghash.io I personally have spread my hashing between the two pools for over a month now. It does seems like ghash.io payout is more consistent and sometime better than btcguild.com, however lately the payout earning from btcguild.com has been consistently better than ghash.io Many can argued that was due to luck, the luck somehow came back to btcguild.com
This is not due to the settings configured differently for the two pools. I would agree that due to the luck level. Sometime it doesn’t have you have 1000 miners pool, versus 100 miners pool, but the luck seems to be consistent on a larger pool, but the payout earning much smaller. Btcguild.com in this case, not so big, but when the luck hit, the payout is nice! it will catch up and exceed ghash.io payout at one point then repeat the cycle.
