Guys, your reported hash rate on the pool webpage is just a close estimate. Go by what your mining software reports and not what the pool reports. If you really want to know exactly how much BTC per GH/s you are making, I would suggest breaking out a calculator and comparing your payouts to the blockchain and pool hash rate vs. net hash rate.
The way I look at mining...if my miners are working properly and the pool is up and reporting....so long as my payouts keep coming, I will keep mining. Go mine with another pool for a few days...chances are, you will come back to Slush pool within a week. Other pools offer merged mining and no registration and other gimmicks to entice miners but I feel the Slush pool is straight forward and one of the best share payout systems I have experienced.
I know the reported hash rate is an estimate, but that isn't the issue for me. The number of shares per worker being shown is an issue, however, and I don't see why the number should go down as well as up. Unless perhaps it is now showing the number of shares which are still earning and have not yet timed out, rather than the number of shares credited since the round started. I never mentioned anything about knowing how much BTC per GH/s I am making, and I'm not interested in that. I am however interested in knowing why my earnings per round are sometimes a quarter or less than in adjacent rounds, even though my shares are a broadly similar percentage of the total (meaning that there was probably no communication breakdown near the end of the round). This used to occur from time to time and was usually corrected before the round was confirmed, but that doesn't seem to happen now.
I have, by the way, been mining in this pool since early last year.
