Stable Datum: The level is over when the EP is achieved.
Quad grades vs Expanded grades? They're the same thing. You stop when the PC achieves the EP of the grade. No sooner, no later. As the PC's viewpoint changes you might run more processes on the grade later, but I wouldn't bother until after OT III and then it can be soloed anyhow.
As for the comments about HSDC vs NED, both are valid. Both should be in current use. If Dianetics Today were revised to reflect the addition of Flow Zero, it would be the best, cheapest textbook-base auditing available. But I doubt that will happen, for PR and historical reasons, since I believe Capt Bill Robertson compiled it. The book was rarely sold actively, because Flow 0 got added in then NED superceded it.
The only impediment to doing metered Dianetics at the bottom of the bridge, where it sat until 1979 or so, is that the auditor wasn't qualified to fly ruds (yes, I know someone above said they were, but not on the HSDC I knew). A Qual OK to Fly Ruds chit would solve that in a trice, or - as was suggested - add the model session and ruds to the checksheet. We used to have to get a student Grades auditor to do it when I was a student, which was nuts.
TP: I didn't ever do the HQS course but once had a girlfriend who did it as her introduction to the subject, and she was very dedicated and swore by that course. Best value for money the orgs ever delivered, by all reports.
As for the emphasis on Objectives, I'd say that's DM dramatizing his tone level - Controlling Bodies. :rofl:
