Hmmmm.
I did it in six-month increments from Jan 2007 (I started uploading mid-Dec '06) until now.
Huge variations, but if these figures are accurate, it looks as though I had 164,979 views from Jan 2007 (when i had about 30 files online) til July 07, then 406,004 views from July - Dec 07, but only 6,911 (sic) views from July - Dec '10, which I'm sure can't be right.
Jan-May 11 is 15,592. The numbers are incredibly up and down - and I've double-checked them. I wonder how accurate it is?
