Index fingers vary wildly in the length though, so how do you account for that? Even taking some idea of an "average" hand is going to assume a lot when you st

  Women's fingers tend to be appreciably thinner, yes, given that this is infantry lore it's safe to say that it's calibrated to men in fighting trim (which implies no extra fat on the fingers). There's still some variation but (the only reason I'm commenting) larger hands tend to be on longer arms, so this normalizes well enough for a rule of thumb. Last point is that with a rangefinder one can calibrate this to one's own body, which is, after all, what gets used as a metric.

    Yes, I am. Sorry I didn't describe that well. It's usually something you demonstrate in person.
