And no, I'm not saying h2o is stealing, all I'm saying that this huge server/user discrepancy should be one of his top priorities if not the top as it seems it just has gotten bigger with time.
If you're on a beta server like I am , Then you will get a lot less, I've noticed it's been happening for a while.
Another thing to consider to is the increased load; just checked the main page for middlecoin and I am seeing 2 GH/s higher than the norm of 19-20 GH/s.
So perhaps that explains a little as well.
