The "mistakes" even out over time, so thats ANOTHER 110% lie. Wow, ,they're non-stop. if they over-estimate this month, then they have to revise it downward the next month. New data comes in every month to provide a more refined estimate.
And they aren't typically "mistakes." They're estimates based upon the evailable data but new data comes in after the initial estimate.
It's very basic math & science.
You should give all the whack job conspiracy theories a break. The wingers are constantly whining about being the victims. Literally everybody is out to "get" them.
