Actually seems like mine just ran! I just went to capture my pre-adjustment number (I was already a million miler at about 1.15 million) and now show 1.8 million. As it happens last night I couldn't sleep for some reason and decided to go through my records to estimate the bump (I have actual records from 2000 and estimates before that). My estimate was almost exactly correct (off by only 16K miles due to pre-2000 estimated values).
I flew a lot of *A and paid C in the last nine years, hence the large adjustment. I have just under 200K lifetime on CO so I should cross 2 MM in 2012.
