Dmitrii Kouznetsov's Tetration Extension

As it is too expensive to compute the contours,
...
One can clearly see the period of -17.14 along the imaginary axis.

How long does it take, to plot \( F(z)-F(z+T) \) ?

   

This is not in scale and took 1562 seconds. You see the difference is in the range of error. But I mean it was already the theoretic result, that it is periodic with \( 2\pi i/\ln(\ln(2)) \) so no need to wonder.
