    It’s fine as an arbitry metric used to evaluate the same population over time.

    It can be used to locate/relativise an individual member of that population within that same population.

    It can’t be used to simply define any given individual in isolation. But it still is.

    Such an extreme outlier is still a valid evaluation in the case though… but only in that the BMI value is extreme, not it’s specific value.
