Terrific, Ricardo!
I do not recall finding this script, it is not my idea, but it has been extremely accurate with all my sims over a few years, and is very truthful with the FFTs.
The advantage of distortion is to compare THD for H2+H3+H4 with THD for 15 harmonics. The percentage of the THD of those three first harmonics is a useful metric for an amp; if above 99%, it indicates there are very few H5 and beyond harmonics.

A new evolution of this design is presented here: https://www.diyaudio.com/forums/sol...et-input-laterals-fast-amp-3.html#post6513605
I am now enjoying a jfet input singleton.
The laterals running at 250mA bias are driven directly from the TIS.
There is a CCS loading the TIS instead of the original bottstrap.
Offset is nulled by a fet opamp servo.
