Is eapm accurate for controller users?

My brother plays on Xbox, we always play together and we’re staying about 1200 team games. His micro is lacking for sure, so he does usually booms and slow push, so he ends with high score and such, and he’s really not a bad player though but his eapm is consistently 10-12. I am just wandering if his eapm on controller is inaccurate and doesn’t register all his actions?
Cause my goodness he would be moving like a turtle 11
