The last couple pages of BC and P2Pool discussions and science has been great.

Sorry to ask this, but what's up with "hitting a block"?

When i was looking into what pool to join, and I saw all the blocks that P2P was
hitting, and at a very high frequency, (luck factor off the charts), I got in just a
couple days after the last block was hit.... bad luck there I guess....

How does the ETA to the next block relate to the the last block, or how is
that estimated?

thank you
