line 1102 where you see if all the values in a series are unique.
sorting might take a while - could you just use https://pandas.pydata.org/docs/reference/api/pandas.Series.nunique.html

Looking at the levels of indentation and the nu,mbersof line in this method near where you calculate threshold masks etc., (lines 742 onwards) , I wonder if it is time to refactor some of this code into a series of functions called something like get_mask_for_aggfuncc()
