The above is a bit unclear, would you care to reword for those of us who are
interested?

Indeed, the ask-finder script seems to return a slightly larger number.

GetResourceSizeOnDisk() supposedly returns the exact size of the resource
as it exists on the disk, not in memory.  From the standpoint of the 
original question, this seems, imho, more appropriate.
