AFAIK, most of the OEM-oriented systems (Bosch, Shimano, Brose, Yamaha, and I believe Panasonic) have each mode mapped to a certain percentage of input power (with the exception of Bosch's eMTB mode, which applies a curve to the assistance), and some systems also consider
angle (that is, when climbing a hill some systems increase the PAS percentage).
