More users joining .. making me earn 16.6% less.. I do hope the extra speed added will make up for it in time it takes to solve blocks.. Do we have an acceleration increase graph I could look at? Speed vs time over amount of shares per hour?
Yeah, me too. The problem appears to be we've got more miners, but not more hash rate. It's still around 60GH, but now we have more miners to split the profit between. Not sure what this new bunch have brought with them, but it doesn't appear to be much

More miners joining shouldn't affect the algo - only total hashrate at any given time.
