If you haven’t calculated it, and you see no need to have someone else calculate it, then it wasn’t such a critical measure, was it?
I don’t care that much about the exact inflation % other than to know that I don’t believe the official numbers. So I invest to make money off it. I know the trend, I know that dollars are being printed faster than physical assets can be produced and I know that the dollar has lost value vs most major curriencies and every commodity that I can think of.
