This is BAD. Plus my share per round has gone from .0028 to .0020 with the pool growing. BOO
Your share of the
reward per round has dropped with an increase in the pool hashrate, but you can expect more rounds per unit time. Your expected
reward per day is unaffected by pool size, only by your hashrate and the network difficulty.
Definitely makes sense to
expect more rounds per unit of time with more power behind the pool, however, that is clearly not how things are playing out in the real-world.
I use "expected" in the mathematical sense, to mean "average". If it's not working out like that, then either you're not allowing enough time for variance to reduce, or you're not taking into account network difficulty changes, or there's a problem at Slush's pool. It's shouldn't be too hard to figure out which if you have enough time and enough data.
