The 0-100 scale must make sense to the retail industry. if an 86 turns to be not such a good bourbon, at least the number is high enough to confuse consumers to buy it anyway. Nobody would want to be associated with a 0 or 1 on Chuck's scale.
I have been confused by this as well, Chuck brought this to my attention, and I've thought about it since I first read this thread. I am glad to be involved with this site. I learn something new every day.
I think Chuck's scale makes sense. It is simple and precise. Retailers love to confuse, keeping us in the gray area. Gray = green to them. Or so I believe.
