That's solvable, tho? iperf3 has --json support, it will give you the b/w readings in the configured intervals (1sec by default). With the interval based samples at hand you should be able to select only the period in which b/w is stable ("middle" of the test). While at it it may make sense to switch to lib/py/load.py wrappers rather than threading the python locally in the test.
