The revision process is a normal part of reporting employment numbers. Since real-time actual numbers aren't feasible, they use approximate and correlated indicators initially and later revise when more solid data arrives.

I can't tell what your point is though. It almost sounds like you're trying to say the initial BLS numbers have been politically manipulated for years since revisions have been consistently down for a while? Surely not, though, because that doesn't make any sense -- continuously applying an upward boost on initial numbers, only to have them consistently revised downward, for several years, would simply cause the system to adjust to the new norm. The absolute numbers have never been important; it's the relative numbers that count, so a consistently applied manipulation effectively becomes no manipulation over time.

Anyway, there's a lack of proof of manipulation. Well, until recently, when the political manipulation was made publicly.

OTOH, I suppose simple facts and logic aren't important in our post-fact world though.
