I have done a lot of comparison tests like this over the years with paint products and unless they did a bunch of tests there is no way it they could say it's the best. It may very well be I have no reason to doubt it, other than I have seen how someone will do something like this and it is hard to be honest with yourself and give something a REAL test against a standard. If these guys only tested it once for instance, it means nothing. It takes a number of tests to come up with an average. So it certainly isn't carved in stone that ATF is the best as far as I am concerned.
