I get that consumer price inflation is a result of monetary inflation mainly via debt. All I'm trying to find is the increase/decrease in cost of consumer goods priced in BTC. If CPI measures price increases, would CPI denominated in BTC not show that?

I also understand that CPI is heavily manipulated, and so is BTC market price data at this point, but what isn't in a fiat world? I like puzzles and this one has a hold of me at the moment.
