Reading this a bit more carefully means the CDC wants up to 8 weeks to have deaths updated.
At the same time, on FluView if it says 100% complete it would still not mean so (or I presume it wouldn't anymore) and I'd have to run all calculations out up to 8 weeks to make sure if changes occur much after that there is a problem and its being done intentionally.
Not that they can't be switching the data during those 8 weeks with intentional manipulation.
