Generally speaking, I think they work (when they work) like this.
All one is really doing as a pc is practicing being in present time. I will speak in absolutes here. To the extent that your attention is in present time it is not spattered all over the universe, or on the argument you had yesterday, or the time you got abused as a child, or whatever. It is available for you to use in your life right here right now.
A racing car driver driving for an hour or two can't take his attention out of present time for very long or he's dead. Anyone doing competitive sports similarly, although it is not usually so lethal, and the higher the level of competition the more intensely in present time you need to be. Some sport like table tennis at competition level, mid-rally, you'd better really be there or you lose the point very quickly. Competition darts you'd better be there at the point of the actual throw, but outside of that you can waffle around without too much trouble.
The longer you spend being in present time on a regular basis, the easier it becomes to stay there when you don't "have to".
So someone who normally lives his life intensely
there isn't going to get a whole lot out of a battery of objectives, and some sluggard maybe will and maybe won't. The idea of overrun takes on a new meaning. There really isn't an EP to an objective process in this view, is there? Beyond that old chestnut for Op Pro By Dup of being able to run it for ever without protest, which I didn't really understand before. The different processes are really just variations on a theme. Hubbard added a lot of significance to them that I don't think needs to be there.
One is not going for a cognition. One is going for the ability of largely being in present time OUT OF SESSION.
Now, I don't see why one needs an auditor to do this, once you get past the dope-off stage. You are drilling being in present time, preferably intensely so, for hours at a time. Why tie up someone else's time? You can probably do it with a video game that demands intense attention and if you waver for half a second you lose. Take a break for a minute every so often--I doubt if it makes a whole lot of difference. But practice being intensely in present time for hour upon hour. Probably much more useful (much more intense) and a whole lot more fucking interesting than Book and Bottle!
Looking at a computer screen that much isn't so good, but hey, many people look at one for eight hours a day with few breaks, so it isn't going to kill you.
Heh. This would makes 300 hours of Objectives really fun as well as useful.
