Just found my fourth block at BTCGUILD!!!!!! WOOT! sorry kinda cool.
edit: 2.18 millions share at the guild and found 4 blocks myself.
So you could have earned ~5 times as much solo-mining, ~5% more on a zero-fee pool or ~10-12% more on a bonus pps pool?
Maybe, maybe not. That's the randomness of Bitcoin, never know what you'll get until you get it.
