Not really. It's inaccurate for some very athletic people, but it is accurate for a vast majority of the population.

It's accurate when measuring populations, where the missing variables average out. It isn't meant to be applied to individuals but is good enough for expedient's sake.

That is untrue. There's no research to support the idea that BMI is a particularly useful tool (compared to, say, neck vs waist circumference) or that the thresholds it sets are meaningful (e.g., that an increase from 24.7 to 24.9 is a lesser or greater increase of risk than an increase from 24.8 to 25.0).

How do we measure how accurate it is or not?

It's not like there is some underlying ground truth on what 'overweight' is, is there?
