IMO - pressure is a combination of two things. First, bumping deer. Second, putting human scent into an area that human scent doesn't usually exist. Now consider this as a scale. The more "pressure" on one side, the less movement you can expect to see on the other. For mature deer, it doesn't take much. The younger the deer, the less pressure willeffecttheir movement.

This is the reason I hunt so many areas, trying to get as many surprise attacks in a season as possible. The number of deer we see is completely dependent on my ability to locate new stand sites throughout the entire season.
