> Whats your experience how stable the RTT of a wireless link is?

This is not designed for wireless.  It's designed to distinguish
a local Ethernet from a tunnel that goes through Tokyo.

We're averaging the RTT on scales on the order of *minutes*, and
considering everything that's below 20ms as equally good.
A completely different algorithm would be needed in order to detect
latency induced by ARQ or by congestion.
