Hi Lars,
then we should define what META-Health means and what not.
To me, it means 
*understanding the interconnectedness of mind, body and environment
*understanding rhythms & phases 
*understanding trauma/UDIN, sensitization/VAKOG triggers, and adaptation
But as META-Health was described as undogmatic, it does not mean one has to agree with all of GNM or with all former Master Trainers may have taught. Where do you think one has not understood META-Health correctly?

Referring to your points:
1. Correct, the Wiki changes in certain points, as science does (However, it can be quoted as per date and time, because it's history is stored and can be reviewed). It also allows for discussion. In science, one refers to specific published articles, which we do hardly have in META-Health. Same is true for Marc's thesis where he refers to the directory without quoting.
2. Correct, but this is not contradicted. She is only delving deeper into that special field, as was permitted to do for a MPE thesis.
3. How does that completely contradict META-Health? The example is what I'd call a myofascial (kinesthetic) trigger by habit.
4. A Lifestyle Prescription is Johannes' term for "therapy plan/action based on the META-meaning".
5. This is a question for Gita to clarify.
