What are correlated noting rates with the pre-vipassana stages? I'm particularly interested in the first stages before Arising/Passing. For example:

Mind and Body: X notes/sec
Cause and Effect: Y notes/sec

I've seen Daniel mention Hz rates sometimes correlated to various stages. But is there a centralized table of correlated rates to stages I could see? How is the data being collected currently? (Eg. a student hitting a drum for every note, EEG, etc.)
