After reading a lot of gear lists on BPL and elsewhere, it seems that camera and fishing gear are always omitted. With those two left out, my base weight is just a few oz. over the 10-pound boundary between "UL" and "Lightweight." In practice, of course, I always take my camera and, unless there are no fish where I'm going, I always take fishing gear (Tenkara, but I have to add a frying pan and extra fuel since I dislike both raw and poached fish and usually backpack where fires are a no-no). That gets me back up to 12 lbs. even for base weight. I'm happy with it!
Being an old lady with arthritis and such, I need a comfortable sleeping pad, although my current KookaBay insulated air pad (3.5" thick) is only 13 oz., not too far out of line. I also get cold easily so probably have a half a pound more "extra clothing" than most. I have some medical problems that require extra toiletries. On the other hand, I've never felt the need for a chair (a sit pad and a log or rock to lean against work just fine for me) or an extra heavy camera.
EDIT, LATER: I forgot to mention that my hiking buddy (also part of my sleep system) is a 70-lb. mostly Labrador retriever. He is much calmer at night in a tent (which he considers _his_ crate) than under a tarp, and certainly deserves his own bug-free space. That means I need a 1.5 to 2 person fully enclosed tent. However, by using a ZPacks Hexamid Twin, I can keep shelter weight, including stakes, down to 17 oz. I've previously used a GG/Tarptent Squall Classic, 27 oz. with stakes. I dearly love the Squall Classic, but was attracted to the Hex Twin by the lighter weight. So far, I really like the Hex Twin, too! I'll decide after a summer and fall with the Hex Twin which one I'm going to sell--it may be a difficult decision!
IMHO, one reason for paring the weight as much as possible elsewhere is to allow for a few extra comforts or hobbies! HYOH and YMMV definitely apply here!
