That probably IS the made up inflation number. (Like ours.)
A better indicator is probably the black market value of the rubble, er, I mean ruble.
There is no “black market” Ruble value because the Ruble is a free-floating currency, which trades on international markets. The concept of “black market” currency price only makes sense in autocratic countries where the government attempts to fix artificial exchange rates. Russia isn’t one of these.
