Gramted, I'm new to this. But according to Slush's site, the payout formula is (25 BTC + block fees - 2% fee) * (shares found by user's workers) / (total shares in current round).

Can someone please check the math on this to see if it holds true to the formula?

Total Shares: 18833717   
My Shares: 1442   
My Reward: 0.00036229
Block# 230220   
Block Value: 25.58996000

By my math the reward should be closer to 0.0019

Thanks!
