It's funny to see so many people having trouble with not looking at it as a grade scale. Since there are so many variables, as well as what someone's idea of a GHB/BOB actually is, the scale was designed to compare apples to oranges. I tried to make it so people could see if they were apple people, orange, or bananna people, if you will. A 70 is not better than a 50, it's just different. I sacraficed in several categories for portability and ease of storage. ie, a two man tent is nice, but I can hack it with a fleece pullover and a poncho. Also, I recognize the importance of fire, maps, etc, but in order to include those categories, I would have to dillute the value of the others to less than a 5% varibale. I thought that would make things too vague for comparison. It seems it would be very easy to overcomplicate this scale.
