I can only make educated comments from hard data and observations I've made myself. I have no data and have never watched individual public land hunters. I strongly suspect those who consistently kill mature bucks on public land are those who are willing to hike the extra distance or enter the most difficult terrain to get away from the crowds. They also probably hunt hard even in the worst conditions. I would bet persistence is a common aspect of their character.
However, I have had the opportunity to watch and analyze data from "club" hunters. This is often interesting because it is the ultimate test of comparative success. All the hunters are hunting the same property. All the hunters are hunting the same bucks. And often, all of the hunters are hunting the same stands (club stands set up for the members with a percentage moved each year). It all comes down to individual choices be each hunter of which stand to hunt on which day. And as stated previously, some hunters are highly successful in these "collective" systems and some are not. Just looking at the observation/harvest data doesn't tell me why some hunters are so consistently success, just that they have an amazing ability to choose the rights stands on the right days. But watching their behavior when they are NOT hunting seems to show a common thread. Those consistently successful hunters are usually the ones I run into post-hunting season, in the middle of the winter. They are out there post-season scouting; putting it all together. They are mapping rubs and scrapes and looking for patterns. They remind me of football players who, after a game, go over game film with a fine-tooth comb, analyzing all of the successes and failures, trying to figure out their opponent's system. They tend to be highly inquisitive people who cannot stand not knowing "why" or "how" about everything. Basically, the type of people who want to take stuff apart to see how it works. And as stated previously, they seem to be the type of people whos minds have excellent pattern recognition; they see the links between seemingly unrelated factors that others do not.
