Methodology:  Up to 100 pages from the top three levels of each Web site were loaded and checked for excessive comments. The graphics referenced by those pages were also loaded and compared to reductions produced by OptiView. Each page or image was only counted once, no matter how often that URL was referenced. The site efficiency rating is derived by combining the efficiency of the home page level with the efficiency of all objects loaded from all levels of the site. For duplicate graphics served on two or more distinct URLs, the additional URLs are rated at zero efficiency.

A rating of "75% efficient" means 1 out of every 4 bytes served is wasted.  A reasonable goal is 95% overall efficiency, with HTML at 98% and every graphic at 90% or better.
