All,

While its really interesting to understand how different image formats
compress and byte boundaries work, it seems to be a different topic than
responsive images and the ideal implementation method, as using optimal or
non-optimal compression techniques to serve different images to a different
breakpoints/screen sizes/screen formats should result in different image
sizes therefore reducing/increasing the overall download size of a page
depending upon the chosen image.

The focus here needs to be more around which techniques will best work for
the wider community on specifying a format/syntax to indicate to the
browser which image to download based upon the screen/user/device viewing
the web page in question.
