Yup, over estimate, its too easy to do.
Here is a buck with a 19" spread, i think he grosses around 125?

There is no way that buck in the pick is near 150, let alone 160, like the man said, it takes a hell of a four point to hit 140.
I still say that deer is closer to 14-15" inside than anything else, still a nice deer.
