Don't be a fool. The other individual was only Lana, who isn't a particularly notable Force User, especially when Zakuul Knights are superior on average anyway. Senya is one of the top Knights, whereas Lana is an above average Sith Lord essentially. Senya would obviously be doing at least half of the work, and probably more than that.
