svnversion does not match repository browser?
===

I'm trying to get the the version number of my code to include in deployment file, but I'm running into a strange situation.  I'm not a very avid user of svn so I may be missing some svn subtlety here.

When I run `svnversion` on the root of my project, or `svnversion c:\dev\calculator` where c:\dev\calculator is the root of my source code, I get the same result: 17597. 

    C:\Dev\Calculator>svn update
    Updating '.':
    At revision 17597.
    
    C:\Dev\Calculator>svnversion
    17597 

However, when I use TortoiseSVN Repository Browser, I see the Revision column for my "Calculator" folder at 17544.  Furthermore, doing a log on the 'Calculator' folder shows me the last log entry at rev 17544 and [the revision graph][1] also confirms this.

Why the discrepancy?  Where is the 17597 number coming from?

Thanks for the clarification!
