for "consistency" I'd be inclined to do the same.
Re audience: if the audience were a pack of crusty academics who'd nit-pick over whether "completed" is meant to be a past-tense verb or an adjective, you'd probably be better advised to use full sentences. < g >

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
