Idea:

a TCP flag to: "look for plateau the then exit"

This would watch for slow start to end, and then run for N (default of 5 or 10) seconds and exit.

Advantages: less test traffic on clean paths

Disadvantages: How to define plateau, and what if there is a big loss event right after N seconds.

This is for discussion.

discussed this, and decided it would be hard to get "right"
