Possible extra explanation: - You've forgotten the denominator Features A and B may be equally important, but B may be applicable only in specific circumstances. If you'd compare A and B on the metric of "how often it's used", you may see B being used much, much less than A, but that's not reflective of the feature, but of the job being done.
