Back when I used to do bend tooling full time, the engineer never really
cared to account for the bend allowances since for our CNC pipe benders,
we had to provide excess length for clamping and then trim the ends afterwards,
so the bent length was used and additional length (4-6") was added for clamping,
etc. Of course if you are working with simpler manual bending machines and want
to do a few bends without having to trim the ends afterwards, I can see your point
in needing to figure bend allowances too.
