When to invoke it: Use when after querying a formula database (KEGG, PubChem, or user-supplied) with neutral mass values derived from observed m/z peaks and adduct transformations, when multiple candidate formulae fall within the configured mass tolerance window (ppm or Da) and you need to rank them by likelihood.
