Regarding just this, in section 3 (Goals), item 3 (User-friendliness), the I-D states that '[u]sers commonly look for a single "score" of their performance.' This can lead to the impression that RPM is intended to provide this single score. I do think that RPM seems more generally useful than either idle latency or maximum bandwidth, but for a more technically minded audience, all three provide useful information to get an impression of the usefulness of a network for different applications.
