Well, I started this because the way it's written is confusing, so much so
that I showed a link [1] from someone who speaks English better than me
saying that PARTIAL is FILTER.
And from the user point of view, who is reading just that page, partial
means incomplete, a subset of, etc. So I think it's easy for the reader to
misunderstand. Whether Parallel Mode is the best term to use here, I don't
know, but I'm convinced that the way it is written is easy to confuse.
