Yes, unfortunately a phrase that's used in an attempt to lend gravitas and/or intimidate people. It sort of vaguely indicates "a complex process you wouldn't be interested in and couldn't possibly understand". At the same time it attempts to disarm any accusation of bias in advance by hinting at purely mechanistic procedures.

Could be the other way around, but I think marketing-speak is taking cues here from legal-ese and especially the US supreme court, where it's frequently used by the justices. They love to talk about "ethical calculus" and the "calculus of stare decisis" as if they were following any rigorous process or believed in precedent if it's not convenient. New translation from original Latin: "we do what we want and do not intend to explain". Calculus, huh? Show your work and point to a real procedure or STFU
