Through all of our miner software tests, we have learned a lot about how the different miners do the developer fee and how many (most!) miners are over-reporting the hash rate (deviation between pool hash rate and reported hash rate). We will focus on some of the most popular miners for now, and all the numbers you will see in the graphs below have dev fees accounted for! First, let's compare the deviation between Gminer, lolMiner, Nbminer, TeamRedMiner and Trex:


If you wonder why we are showing the graph for T-Rex 0.24.7 - more about that later!
You can also see luck's effect when comparing different runs from the same miner software. When the number of shares is low (the beginning of the runs / left on the graph), luck plays a huge role - and we get considerable variation between the different runs. As the tests run longer and find more and more shares, the chance becomes a much less factor, and the lines are closing in. This is why we run our miner software tests at a minimum of 1.000.000 shares! Taking a look at the graph below, it seems like GMiner are doing continuous fee, so we are not able to recognize the pulsing as we do with miners who stop the current mining and mine for the developer for some time, before resuming the regular mining (See examples below with NBMiner and T-rex)
