The npmax clarification makes sense, but why is "xkin" better than "Xk" in the description for G and H?

I was thinking because xkin is declared on line 19 it is clearer. Otherwise, Xk isn't used anywhere else in the docstring, right? (I can remove that edit if you prefer.)

That wording is even better. Thanks @mmenickelly
