I found this information:

http://ramugedia.com/hls--how-determine-peak-bitrate
(which doesn't point to any source for this info).

It does look scriptable. It would be more difficult to implement for
ffmpeg, as the hls demuxer would need to keep a memory of each
segment's properties, and do the math at the end, but perhaps not
impossible.
