I can't. I only noticed the discrepancy after you posted the final prize amount and remember that the final prize amount was about 490+. I have been checking the site the last few days but I could not tell that the amount was off by 25btc at anytime if any. I had no reason to believe otherwise and had no reference to compare the amount.

As for SatoshiDice, I haven't used the site so I do not know.

I think you will always get deposits made by mistake and have to make adjustments so the site should always check for address balance not the total amount received.
