Tried Ozcoin and I have not done the math but in just looking at the numbers over the past 24 hours it doesn't look like I am earning near as much as on say eligius. Sure pool vs. pool things are going to be different but my quick BTC balance divided by 24 hours seems to show almost 1/3 less mining potential on Ozcoin as Eligius.
Am I in the ballpark, math is off or just nuts?
As the others have said you need to give DGM some time. It pays less up front and more in the middle and keeps paying for a bit after you quit. That's how it attempts to ameliorate variance caused by what the BTC community has termed "luck".
Besides that there have been a few VERY long rounds in this 24 hour period on Ozco so that will hurt quite a bit too. So try and take that into account. There have been periods that Ozco has been paying better than Proportional or PPS pools. But still it tends to even out in the end.
The only way I can think of to get a really accurate comparison between pools is to mine two different pools for an entire difficulty period with two separate rigs configured the same on the same internet connection. But even that is not completely accurate since two different GPU's of the same model and manufacturing run will still have different performance characteristics.
It's really hard to compare apples to apples in Bitcoin mining. Which is what brings it value.
