SgtRock, welcome to the forum. Market Hunting is something from our past. The only reference to Market hunting I have heard in quite some time, was the mis-use of the term to describe the practice of guided hunts on private land. To the best of my knowledge, Market hunting is not used today, in this country, so you will get no argument from me.
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.
