High-frequency-resolution waterfalls falsely suggest uncontrolled ringing

Evidence

All these studies indicate that parametric equalization based on high resolution steady-state frequency responses is a reliable method to attenuate bothersome room resonances. Waterfall diagrams alone are of little value in estimating the audible consequences of resonances. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1654 (#corroborates, via linked claim)
