you can get something like this to help you see better:

you could ask for these at your pharmacy, but if you want to order through ADW (the link) sign up first at mrrebates.com and you'll get a rebate on any orders from ADW. it adds up.
you can also find counter-top or clip on (to a cupboard door?) craft magnifiers at any craft store.
i think it looks like a bounce. am i remembering right that you are pretty afraid of her going too low? because on 10/10 she had a great response to the 1.5unit, but you dropped the dose because you were afraid of the 184 preshot number. you went back up to 1.5 in the morning, and it looks like she was starting to respond to it again and you got a 176 on 10/13's pmps. if i were guessing, i'd guess she got lower the night of 10/13 and bounced up from it. then you raised the dose to 2.0 before the bounce had a chance to clear, which has kept her up. a cat can bounce from any number range that they aren't used to, and then if you increase the dose, it creates a sustained kind of bounce in higher numbers.
also, anytime you've got a shot off of the 12/12 schedule i think you could expect to have to wait things out until she resettles again. i'd suspect those couple of times when you had to adjust her shot time might have figured into this as well.
see what others with more experience than me say, but i think if i were you, i'd drop her back to the 1.5 and let her settle and see what that 1.5 really does. make sure you get an evening +3-6 test every single night. pick up some kind of magnifying glass so you can increase her only by .25 units, because it looks like she might be really touchy to the insulin and probably only needs slight adjustments.
just from my looking at her ss, i'd guess she is very responsive to the lantus changes. the .5 change is too much for her, she needs her shots 12/12, she's bouncing from going into the 100's, that kind of thing. can you see any of that if you look?
also, i know you've said you want to do the start slow plan, but if you want her to go OTJ you will have to summon up your courage and shoot numbers in the 100's. it is part of the plan. just make sure you are monitoring her - a before bed check would do a lot towards giving more information so we could guess better on what's going on here. and always when you shoot lower than you have before, get tests at +1, +2, +3 hours to see where she's going. you can learn to steer her with high carb foods and karo syrup and as long as you are testing and monitoring her, she won't be in danger.
