Is the EPA setting relative to the kv rating of the motor?

case 1: A 4000 kv motor at 4S EPA 100%. Motor has max efficiency at 40k rpm. The rotor will be turning at 59.2K rpm which obviously is going to heat up the motor and possibly over work the esc.

case 2: The same motor at 4S at EPA 67.5%. Assume that the motor is running at 40K rpm which is at the max efficiency rpm. Motor will be running cooler and not overloading the esc.

Will the above be true?
