US Digital defines "CPR" as "cycles per revolution". It's the same value whether you're talking about one channel or two. And there's no ambiguity concerning rising and falling edges.

If "CPR" is defined as "counts per revolution", the number is ambiguous unless you specify whether it's one channel or two, and whether you're counting only rising (or falling) edges or both.
