Slush's pool payout glitch?

[dmphotog]

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!

Shares submitted most recently before the found block are paid at a much higher rate than shares found early in the shift. You probably had more shares in the earlier part of the shift than in the later part.

Sorry, but all of the other blocks have been coming in with good math except this one.  It is WAY off.  Besides, what you stated does not fit the formula that he is going by.
