I have had plenty of experience post 1979. Just hitting a few high points here, before 1979 I learned to run only reading questions and items, F/N everything, and, ah, TR-3.
I learned to prepcheck by simply asking the question, then when the pc runs out of answers, check the question against the meter. Move on if no read.
For years it worked GREAT!
Then only running questions that read, it worked not so great. I argued with Class 8's over that, and argued with whomever was sitting in for LRH on the SO#1 line.
Last I heard from anyone at Flag, I was said to have been "squirreling in the field for years."
Oh, well...
I like your expanded prepcheck questions. They give pc's a lot to talk about without undue pressure.
My present attitude, one I have had for some time now, is that anything can be run whether it reads on meter or not as long as the pc is running what he is interested in and as long as he is not being overly controlled down some path that he feels is irrelevant. Also, it is not necessary to "F/N everything." It is only necessary for the auditor to run what pc is interested in running, and complete auditing cycles as best as possible.
A pressurized TR-3 creates synthetic valences of some people. They become someone else to be able to receive a session.
The last person I cleared I think I used TR-3 maybe once, and TR-4 just once. That says a lot for the willingness and trust of the pc, and pc+auditor being greater than bank.
Also, I might do a worksheet for my own guidance. When the processing is complete the sheets are destroyed -- excepting L&N's.
We don't need no stinking worksheets if we are auditing the pc in front of us, the pc who can change in a flash thus immediately stale-dating any C/S that might have been correct at start of session.
About Flag being the mecca of technical perfection...
