You'd have to ask people who use %P: how do they use it?  Why (or what for)?
Maybe it's OK to have %P represent B/(A+B), or maybe a better solution
would be to offer access to A/(A+B) as well as (TOTAL-A-B)/TOTAL
(i.e. percentage of buffer shown).

I don't think it's urgent, so we should take the time to try and figure
out what %P users want.
