No one has confirmed it for me but my opinion of setting it to half is so that you can retain utmost filesize predictability, eg. the rc averaging period ends on or very close to the end frame.

I'd never heard it explained this way, it may well be true but I don't know. It sounds reasonable to me. I
have noticed like you have that my files come out exactly perfect size this way. Out of curiosity, if you are correct about how this works, why not set the RC averaging to exactly the number of credits? Wouldn't this also do the same thing? Say, for example, a movie has high motion for the first half and low motion for the second half. If you had RC at half, even though it distributes bits well in each half, the second should get less overall... Or am I misunderstanding what the period does?
