Well, the way we defined it [1] is:
- in absence of any other signals, we would use the theoretical max DL rate
- if we can refine the upper bound (e.g. WiFi drivers do communicate max
rate based on RSSI), then we would communicate that value

As such, the intent is to communicate the upper bound (with respect to
first network hop) to the best of our abilities.
