Obviously the calculated reward is a perfect case scenario, you will never get so many.
Suprnova pool luck is 120% for the last 24h, that means 919 coins per day. Minus the difference between hashrate in your miner and on pool, not all shares are accepted.
So always reduce the value by pool luck and a couple more percents.
