Wildly inaccurate?

How happy would central banker be if they could get outcomes within 10% of their planned goals?

A central banker could easily achieve a perfectly accurate prediction of the amount of currency available, which is the type of prediction we're talking about. They print the money, so they can just print according to their predictions.

The types of central banking predictions that are usually criticized are predictions of prices in the economy. Bitcoin fares no better there.

Not really. Banks and corporations hold reserves, lend "money" that's actually debt between banks not backed by hard currency, pay debt directly to the central bank... it's not that easy. At a given time, there are many "amounts of currency" coexisting at the same time.

Right. I was trying to choose straightforward terms that would make it clear that I was referring to the monetary base, not any other measure of the money supply. I guess that didn't work.
