Cool trick. But you can easily plot the input impedance against frequency by doing an ac analysis and plotting V(in) /I(c1) and change the vertical axis to ohm. You can do the same trick for the output impedance by moving V(in) to the output and shorting the input to ground. This way there is no calculation needed.
