For users the most important things are going to be the on-page image sizes, the background image is normally the last to load.
For spiders everything apart from the basic page size is irrelevant, and to be honest I thought that tool was more aimed at the "optimising pages for spiders" crowd than the regular webmasters.
But still since it does do some image work it seems a little strange that it doesn't do it fully!
