Isn't the fact that every time you track, you judge the track in some way? Direciton of travel, speed, etc. And pressure releases are just one attempt to explain and catalogue that judgementprocess. It helps to have a common language when describing a complicated process, especially one that is based on judgement and guessing based on experience.
You can use pressure releases in tracks to determine where the next track is. Ie. by examining the one track, you can determine the speed and direction the track is going, thus you will have a good estimate where the next track should be. If it's not there or in the vicinity, backtrack and go more slowly, if its there, repeat.
But if you are hunting (with camera or with gun and go examining every single track in minute detail, the trail will be cold, frozen, buried and eroded by the time you get close to the goal.
Pressure releases does contain a lot of information.. IF you want it. But that goes for all kinds of tracks. Scat droppings for example can fast give you an estimate of how recent the track is by how eroded the scat is. But it can also give you an estimate of the diet and even the health of the animal. This however isn't really useful information if you are just pursuing an animal. Same goes for middens or scrapes aswell.
So, don't be discouraged if an experienced tracker don't know what you are talking about when you mention pressure releases. He probably uses them without knowing the "scientifical" term for it When tracking for a long time (or to put it like Brown does, with a lot of "dirt time") the ability to judge a track becomes an instinct.
In the beginning however, its useful to get down in the dirt (or snow Abbe just to see how it all works.
