Not only is the term "net satisfied" a total misrepresentation but the figure itself is no longer a fraction of 100 ie; "per cent" meaning per 100. It's a trick of both language and mathematics producing a bogus result which is as you say - ripened fruit for journalistic misrepresentation - offered to them on a silver platter. A ranking can be easily assigned (even using the same equation) if they so choose ... without describing it as a "net satisfaction" percentage - which it's not.
