Well maybe, but it wasn't the only node contributing blocks to the chain. It looks like the "erundook" nodes combined represent the 1200 MH/s that was on one fork, and my pool had ~60% on the second.
Exactly that. I think wdc.dontmine.me was on it's own fork for about 80 blocks.
his page says that it was about 300 blocks. Damn, there goes some cash money!
