Below is a copy of my bet at MyriadCoins.com. If my chances of winning were 88% then did I really have to be within 4400 of the chosen number? Just doing simple math it seems like I'd only have to be within about 8800 of the chosen number assuming there are 9999 possibilities. Can anyone explain why my rough estimation is so far off?

Also where do you go to use the hash to verify the outcome? I know the numbers wrap around and it just occurred to me that 4400 is exactly half of 8800 but I'm still not getting it?!?!
