Thanks, all.
For this go-around, 15 months for everything. There was a remaining disability to be adjudicated on a prior claim, and I claimed TDIU during that process. The Cleveland Tiger Team pulled it from my local VARO, who (charitable mode: ON) were apparently swamped and just unable to get to it for a year. The Tiger Team handled it in 3 months, give or take a day. I also have to say that the VA point of contact at Cleveland was a genuinely pleasant person to deal with, gave accurate answers to questions, and they basically need to just clone him and have at least one of him at all the other VA offices. This is my second experience with Cleveland, both positive.
Having supportive comments re TDIU from my treating doc AND the C&P doc was helpful, if not crucial. I believe my "avoid calling VA when I'm cranky" rule is a good one, too. I think It helps me keep folks on my side (or at least not actively rooting/working against me) during the process.
Fortunately, I'm length of service retired from the Air Force so ID cards and CHAMPVA aren't issues for me. Property tax is, and car tags, etc. will be. Paying off bills felt good (got the back pay today!) and not having those recurring expenses will be an additional monthly "raise."
