I know I'm not supposed to "spam link" to my own site, but I'll be damned if I'm gonna write out the whole thing again (even pasting).
Here's a taste, anyway...
OK, in some ways this is gonna make my previous Medicaid analysis (which was confirmed by the CMS a few days later) seem like kid's play, but in other ways it'll actually be far easier to follow. Not only have I prepared multiple screen shots of the spreadsheet involved so you can see exactly what numbers changed and why, but there's far less guesswork on my part as to which cells to keep or eliminate. All of the relevant reports, along with the actual spreadsheet itself (with all 6 worksheets) are linked to at the end of this screed.
You see, while my 6.3M figure from several days ago does match the 6.3M total that CMS announced yestereday, there are still some anomolies, because my 6.3M includes some additional data that's been released since the end of December, while their 6.3M includes the December "direct ernrollment" data for all 50 states that I didn't have access to. There are some additional factors to sort out, and I decided to start from scratch to figure out what they were. What I found surprised me.
