Predefined bitrate of VBR files

Ollekebolleke
For audio files encoded with fixed bitrate it's clear that the programs shows this value as encoding bitrate.

However, I'm wondering what the program shows when a variable bitrate is used. Is this the maximum, minimum or average used bitrate of the file? And is this value calculated by the program by analyzing all frames or taken from a VBR tag?

It's the average bitrate; this is calculated by the tagging-engine and should be
bitrate=size*8/duration
(where size does only contain the audio, not tagging-data)
