You have to also consider the (hard to measure) rate at which Bitcoin is accidentally lost or intentionally destroyed, which is a deflationary pressure. "2%" is target for the growth in the ratio of money supply to product supply, not the money supply itself. BTC could be wildly above or below 3.7% (+/- deflation due to destruction) based on the growth of the GDP of the BTC-financed economy. In short, those two metrics are just not comparable types. BTC has no "target" inflation. At best, you could measure BTC's observed inflation.
