The discrepancy between the 2004 and 2017 power-spectrum formulas for quantum spectra is resolved: either result is correct depending on how unfolding is performed, and the 2017 correction needs over 1000 realizations to matter.

Stringent Test on Power Spectrum of Quantum Integrable and Chaotic Systems
The discrepancy between the 2004 and 2017 power-spectrum formulas for quantum spectra is resolved: either result is correct depending on how unfolding is performed, and the 2017 correction needs over 1000 realizations to matter.
