Since the administration have stopped releasing some data that usually is released, how fast would people be able to notice that the economy tanked, if it did?

Well technically, the economy has tanked (sort of), people say that the economy's doing great but the figures that we see in (q4?) are extrapolated from the previous quaters in which the only thing (from what people tell me) is keeping the "illusion" of economy doing good is the spending within AI datacenters. But a huge part of that is shrouded within mystery as well (Stargate project is really suspicious in my honest opinion though I can be wrong)

Also wasn't there some BLS figure which was pushed by the Administration to try to have good numbers or similar. I mean speaking from a different countries pov, Personally I wouldn't trust the numbers the current administration gives.

I don't know if this is the same belief that Americans within America also hold though.
