I don't think that CSS sprites should be bigger, given that css is improving, I don't know about the sample analysed, but usually the editorial and user-contributed content images (as well as ads) take much more bandwidth than style related images, unless the site has exotic design.
aside: kranken.io is nice
Sidenote: I found out about kraken.io on HN a while ago. I use it for all my images now. Usually gets at least 5% reduction on a well created picture, and 50%+ on a bad one. (No affiliate, just like it)
