Unfortunately what this reader does not understand is the constraints placed on the Author by the editor for space. I would figure that to place all of the available information on these tests would have called for pages in the magazine and that is just not reality. The manufacturers themselves can supply you with their own info. As an outdoorsman who has participated in testing such as this I can assure you that we even bring in forensics experts to attain the highest and most varied testing possible and without involvement or influence of the manufacturers themselves.
