Modifier adverbs shift degree of set membership by fixed mathematical inequalities

Evidence

Ireland might be a 1.0 member of the set of wealthy countries, but only a 0.75 member of the set of very wealthy countries. Mathematically this means that the score of a given country, such as Ireland, for very wealthy is less than (or equal to) its value for the concept of wealthy, e.g., 0.75 < 1.0. — Gary Goertz, Social Science Concepts and Measurement, 692
