Welcome to the forum.
There is no truth to that statement. There is no way to tell what any piticular deer will produce. I believe that has more to do with nutrition, than anything else. I am a meat hunter, and don't care much about bone, but I'm sure the experts will kick in and tell you all you ever wanted to know about bones.
Enjoy the forum, I do.
The only real difference between a good tracker and a bad tracker is observation. All the same data is present for both. The rest is understanding what you are seeing.
