Hello Everyone.
     I started an Excel worksheet with my view and download stats.  This not only allows me to check the percentage of downloads per view, but also allows me check the percentages between date.  I just have the differences between two dates calculated, and generate a percentage based on that.  It will give me a good idea of if I am advertising my pages correctly (Not misleading).  The higher the percentage, the better I am doing.  If you only have a few files, you may want to do the same.  If you have a lot of files, updating the worksheet would be too much work.
