None of them are based on anything though. Theyre curve fitting models which is why I am hostile to them. Show me a mechanism that derives what a0 is from scratch.

Basing a model on how well it fits a curve rather than on a mechanism that naturally derives the curve from scratch is essentially worthless.

Without a mechanism that explains why there needs to be a MOND dominated regime in the first place, its just too susceptible to being pathological science.
