Re: Maybe try interest
Whatever the receiver of the auditing is most interested in should be a safe guide, whether solo or delivering to another.
Maybe a simple "interest scale" of 1-3 etc. It would be a snap for solo. For delivering to another, it would take a little thought but you could devise some kind of system for assessing and managing by interest combined with very close observation of the pc.
If you know your stuff you don't need a meter. So I've heard.

In psychology, the scale you might want to look at is "subjective units of distress", or "suds" scale. It's a 1-10 rating of distress on an issue. These tests are used in clinical trials as ONE of the measures to determine whether an issue is still troubling a person, has gotten worse, or has gotten better (before and after, sometimes including another check at six months, 2 years, 5 years, 10 years, 20 years, etc.).
I use this sort of measurement with viewers. Instead of doing a metered assessment. "Tell me some people, places, or issues that are stressing you out" is one of my interview questions. It can be worded in whatever manner gets the person to look and list what needs to be handled. Once the items are all on record, then I have them look at them all and rate them on a SUDS scale. Once they tell me what has their interest, off we go. Then, later, once that is handled, move along to the next, and ask if that order is still correct, if they are still interested in handling. Keep going. When you're finished, you're finished.
After that, if you want to go spelunking (and I like to) into Grades type areas, well, I'm fine with that, but not at the expense of the person re-engaging with their life. Solo, IMO, is a great way to find total delusion. You might be totally free in your mind, but in reality, you are losing touch with the world around you. There are faster ways to do that.
