Calculum Rationale
From Warhammer 40k - Lexicanum
The Calculum Rationale is the in-depth, detailed and meticulous process of calculation by which the Iron Hands decide exactly how many resources will be required to prevail a given battle or campaign. If the calculation results indicate that there are insufficient resources, the Iron Hands will refuse to participate in the battle or campaign.[1]
