Yeah I've heard the same thing and looked on Google and you're right, that's what it says. But I just looked through a bunch of pics of fish I know were saugeye because of where they were caught and all the tails I could see had at least some white on the tip of the tail. Might not be as pronounced as on a pure walleye but it's there. That's why I'm saying I can't ever tell 100% and don't even try.
