We take it a step further and correlate it with the application (some of which are more sensitive to RTT than others), as hinted in our paper at the IAB workshop: https://www.iab.org/wp-content/IAB-uploads/2021/09/CanopusPositionPaperCame= raReady.pdf I can also add that we continually measure RTT not just for TCP traffic, but also for UDP streams, particularly gaming, as profiled in our most recent OMG!
