How long will it take me to generate a block?No-one can say exactly. There is a generation calculator that will tell you how long it might take.

What if I'm 1% towards calculating a block and...?There's no such thing as being 1% towards solving a block. You don't make progress towards solving it. After working on it for 24 hours, your chances of solving it are equal to what your chances were at the start or at any moment. Believing otherwise is what's known as the Gambler's fallacy [1].

It's like trying to flip 53 coins at once and have them all come up heads. Each time you try, your chances of success are the same.

So.. mining at slush's pool also is a gamble.
Just it is "more stable" gamlbe ; )
And since p2pool overall hashrate is not so big, the stats could look bizzare.

Right?

What I don't get is
Lets assume there are only two miners in the network miner#1 has 10000GHs and miner#2 has 1Hs and some calculator tells that miner#2 supposed to mine a block in a 24hours.
Now, since each block is created every 10 minutes(in our case miner#1 will generate them) and after each new block the work should be restarted, is it fair to say that miner#2 never generates a block?
