Rising F0 lowers resolved harmonic interactions and worsens pitch extraction

Evidence

In each case, the highest common factor of the components is f0. This method also provides a basis for understanding how a pitch is perceived for non-harmonic sounds, such as bells or chime bars, whose components are not exact harmonics (integer multipliers) of the resulting f0. — David Howard, Jamie Angus, coustics and Psychoacoustics, 864 (#expands, via linked claim)
