This has been beaten to death the last few pages. It all depends on what server you're on, your settings, your time on that server, etc.
You could only compare apples to apples if we all split hashrate equally instead of just for the coin you're mining.
No matter what server they are on, they are submitting the same amount of accepted shares I am (hence the same hashrate). So I can understand if he had more unexchanged with a lower balance (in the end they all are about equal). Also, h2o said that all servers are running the same thing now, so none of the servers would be more profitable than the others
