LISA (an acronym for Logic Inversion Scorination Algorithm) is a scorinator, initially created for association football with an adapted version also existing for basketball.

It works by converting input rank (ranking points plus RP bonus) for each team into an Elo rating value, and using the difference between these values as the basis for calculating win probabilities; there are then further calculations to determine the winning margin (if any) and the number of goals scored by the losing team (to which the winning margin is added for the winning team; in the event of a draw, this value is 0 and so the "losing" and "winning" team scores are identical). This differs from traditional scorination methods for association football, which derives the score for each team from a series of "attacks" with a given probability of producing a goal.

The formula for converting input rank into Elo incorporates multiple user-adjustable constants, allowing for notably different interpretations of LISA.

A basketball adaptation (referred to as LISA-HE) was used for the first time in NSCAA 17. It notably allows for the incorporation of home advantage and style modifiers, neither of which are supported by the xkoranate basketball formula.
