When I scout, I mark what I see on maps (GPS makes it easy but I did it manually before the GPS). All of the scrapes, rubs, trails, beds, poops, stuff like that so I get a good idea of their movement patterns. I know where they'll eat, usually, depending on what is available. Once you can see all of this stuff on a map it makes it easy to see good patterns. Then, what you need to do is discern when those patterns are active.

I think it is not always how much you scout but how you scout and what you do with the info gleaned from scouting. I do scout a lot though.

This map has changed a bit from this picture but you get the idea:
