Well that’s tough to say, because it depends on how you’re defining inflation. It sounds like you’re just concerned with CPI including food and energy. This is referred to as “headline” inflation (as opposed to “core” inflation, which is what I’m guessing you’re trying to avoid.)
But again, those are still just a basket of prices. If you’re going by the pre-2003 definition of inflation (an increase in the money supply), then you need to look no further than the money aggregates. Of course, the Austrians have their own definition of “money supply” as well. (For more info, check out the links here.)
Mark Skousen talks about this here:
What’s the Best Measure of Inflation?
And there are of course plenty of other sources on this:
Don’t Believe Those Inflation Numbers
Smoke, Mirrors, and Inflation Expectations
Those last two are by Frank Shostak, who has written quite a bit on the subject. You might check his archive. And here’s a great interview with Jeff Tucker and Shostak in which the economist talks about how Austrian theory combined with an analysis of money supply make for an excellent forecasting model.
