Either way, what I'll do is to remove this special return value for this
series, and add it back in the perf series if needed.
This is one of the problems that arises when you take a series with
lots of changes and try to break it apart. You will always miss
something that isn't needed in one where a change was made for another
series.
Working on each one to make sure this all works, it starts to blend together :-p
