Nicolas George already answered you the 23th about required documentation.
In my opinion, there is today a commonplace definition of max bitrate that involves computation over a sliding window of 1s. This is reinforced by ISO/MP4 (14496-12), but even in the broadcast industry with the MXF file format, this is currently how a max bitrate is understood.
I fear that introducing another method of computation will raise some confusion for many end users.
Nicolas
