This show the amp is not symmetrical in its response to saturation, which is due to the driver stage. It would be nice to be able to make tables using 2 parameters, a sig_max and a sig_min.
pyplot does always plot from low to high, hence the table start at -20.
The logic I've implemented for interpolate the table was only good for positive signals. I guess that is a big part of the difference you've seen.
I've now pushed a new version to git, introduce two new options,
-g N or --table_neg N = build negative nonlinear response table from the N\'t circuit
-S or --scip_div = skip the divider for the negative nonlinear response table
the divider is used to translate the table into the digital domain (0 <-> 1) , default is, that the divider calculated for the positive sig, get used for the negative sig as well, you could scip that and a new divider will be calculated for the negative table.
--table_neg N were N is the number of the schematic you'll generate a negative table for. You could generate multiple as before with --table 1 2 3 . .
but, when a negative table is generated, a positive will be generated (and used) as well.
On the road again.
