My guess is that the server is lying about the file size but not in a 
way that wget expectes it to.  Wget attempts to work out if the server 
reports the total size of the file after the REST command, or the 
remaining size, then compensates accordingly and gives its own 
(unauthoratitive) calculation of how much is left to download based on 
this figure.

I shouldn't think this should be a problem provided the server is 
restarting the download in the right place.

Try starting wget with debug output (-d) and see if there are any more 
informative messages.
