Calculation method
Calculation method
Pairwise crossover shares in requested range
Let α be the varied share. Keep other criteria proportional to their base weights. Solve each option-pair affine score difference for zero and retain crossovers in the inclusive range.
Best option(s) at sampled shares
Evaluate α at the requested equally spaced points; exact ties remain visible.
Option scores at minimum and maximum shares
Evaluate each option at the two range endpoints.

Assumptions & limits
Assumptions & limits
- A one-criterion sensitivity sweep under fixed scores and proportional remaining weights. Pairwise crossovers need not change the overall winner. It does not infer preferred weights or score uncertainty.
