Transformed scientific name match score (SNMStr) versus original, untransformed score (SNMS) of a submitted binomial, showing the differing degrees of certainty defined by the transformation function. In the two regions of certainty, small score differences have a smaller impact on the outcome: either there is a mismatch (SNMS=-2) or a perfect match (SNMS=2). Similarly, in the region of uncertainty, small score differences do not help to distinguish between matches and mismatches. In the regions of discrimination, instead, there is already a preference towards matches or mismatches, and small differences can help tip the balance.
