Has anybody any information about the performances of wavefunction and charge extrapolation (options wfc_extrapolation, pot_extrapolation='first-order', 'second-order') in PWscf? I am wondering if it makes sense to keep it, in the absence of any evidence that in at least some cases it makes the calculation faster.
