It's not just -c that adds the 10000:

  mkpasswd.exe -d $USERDOMAIN -u $USERNAME

also gives a uid that is RID+10000.

The ntsec page mentions using mkpasswd and mkgroup but does not explain how 
the uid or gid is chosen. I think my comment was prompted by the mention of 
numbers of 4 digits earlier in this thread. Having a 6-digit RID for my 
domain account I can see that the uid generation does straightforward 
arithmetic and not some sort of string processing. (Is it really 19106 this 
year? Some people wrote code that thinks so.)
