I really like your site, neat idea behind it. I have seen others that focus on amount of blocks solved. But to go on the side of how much the miner would make is a interesting perspective.
I hope you keep the site going. This might cause me to try a different pool.
the only way this site would do you any good is if you had a time machine and you could go back in time and pick the most luckiest pool.
these graphs dont tell you anything useful as far as what one would be the best pool tomorrow.
