To emphasise for others who might not realise: this fast "Taylor expansion" method is now no longer really needed in most cases, since the "evaluation" is now vastly faster than it was before.  This is for standard, "normal" BBH parameters.  It might be different for more extreme cases.  Also, the "Taylor expansion" method leads to significant noise in the solution, which you can see if you look at high derivatives of the solution (e.g. Psi4), or subtract solutions at different resolutions.
