How is she going to know the workout is having the desired effect if all she does is look at the HRM? Without RPE, it is just a number.
They are all just numbers.

I don't know how you could ride without thinking about your perceived exertion, unless you're totally disconnecting from your body as you ride.

BTW my experience at altitude has been the opposite. My HR gets higher, not lower.
