I guess in a nut shell some can tell the difference and some can,t.
That's what it boils down to. Reading tracks is like anything else, it takes practice. It takes a trained eye with an attention to detail. Nobody can claim to be right 100% of the time, but the more practice you get the more accurate you will become. I am no expert tracker, but from the responses here I would guess most haven't had the opportunity or desire to try tracking.
