hvh_validated is part of the quantity the equation computes from the expression on the right.

The passage around this formula

…are nearly the same population, because everything proposed gets made. For DFT and ML screening, the denominator is enormous and the numerator is whatever small subset anyone bothered to attempt — so a favorable-looking hvalidatedh_{\text{validated}} for a screening method usually reflects a tiny, favorably selected numerator rather than a property of the whole candidate pool.
