John does post a lot of useful information on his website and it is a great resource for many folks.
So my thoughts and PLEASE, I am not being critical of John.
To me the value of posting a gear list is for others to see how gear can work as a system. The value of a gear list for most is how it can be used in varying conditions (3 seasons), with an eye to the variables in terrain, weather, etc. A gear list should be able to handle a trip of 2 to 7 days with the only variable being how much food is required.
I often do trips of a couple days in perfect weather that have base weights of ~2 lbs... but that is not useful to anyone except me on the specific trip.
IMO, to be valuable, a 3 season gear list should be inclusive of gear to handle rain and temps down to freezing. The hiker can remain warm, dry, and safe.
A couple years ago I posted a trip report of 3 days that included rain and low nighttime temps at freezing. FSO weight, excluding consumables it was under 5 lbs and included shelter, 32F quilt, rain gear, sleep pad, and a reasonable (IMO) FAK. Many folks found this useful -- although maybe a little spartan for their own use.
Of course, anyone can find fault with any gear list... opinions are plentiful.
