When omitted

ComputedTakes the value of TargetEffectivenessCoefficientDefault in [General], which is itself 0 when that key is absent too.

The coefficient multiplies the Verses percentage of the weapon the candidate would choose against this object, measured against this object’s own armor class — how badly the candidate could hurt the object that is choosing. A positive value draws fire toward dangerous candidates. It is read from the type of the object doing the choosing, never from the candidate’s type; a candidate with no weapon, or one whose weapon carries no warhead, contributes nothing to this term.

The sign flips for a candidate that is already shooting at this object

This is the one term whose result is negated rather than added when the candidate’s current target is this object, so an otherwise identical bystander outscores the object’s own attacker by twice the term. A positive coefficient, set to make an object prefer whatever can hurt it, therefore steers it away from the thing hurting it.

Zero cannot be pinned on one type

The value is read with a fallback that substitutes TargetEffectivenessCoefficientDefault whenever the stored figure is zero, and the rules are read again for each later layer. An explicit 0 therefore lasts only until the first later layer that carries the type’s section without this key, which puts the global default back.
