Haha, shhhhhhh.

I think the confusion comes from reported hash rate. People see their miners settling in at 40, 200, and 700, and expect to see, 940kh/s all the time. But what's easy to forget is that with harder work, when submitted, you get more shares. So while it takes longer to submit work, submitted work should average out to the same number of shares. I can't see my average shares over the last 2 weeks vs the last 8 hours. I'll just have to trust the math.

I think the biggest thing is this: Because shares per round is fluctuating so much, reported hash rate is also fluctuating. Shares over time should average out to being the same, thus reported hash rate should average out to being the same.

I should have just done more research before speaking. Sorry about that. :-)
