To find your BTC per Block, use Kano's calculator
http://tradebtc.net/bitcalc.php, put in your TH/s and hit calculate. Then take (BTC to expect per Day per TH/s) divided by (Pool Average Blocks per Day) times (your TH/s) and it should give you your expected BTC per Block at the current hashrate.
yea I tried that, it looks like gibberish to me - hence why I asked.
Thanks though.
