I have mined at three other pools before joining middlecoin a few days ago. So far, I'm seeing less profit than the other pools I had mined before. Why is that? Could it be because the difficulty of 512 is too high for my miners? I have 4 GPU's: 1x6950, 1x7790, 1x7850, 1x7950. On other pools, I got about 1300 KH/S. Here, I'm getting 1000 KH/S. The other pools operated with vardiff; here, there's only one difficulty of 512.
You can talk statistics and probability and whatnot all day and night long. I can tell you from my day-to-day experience that this pool with a high diff set at 512 runs very inefficiently for me. Probably because of my gpus can't hash fast enough for the pool. I am going to have to return back to wemineltc.
