Why not just have the user specify the capacitance of the capacitor on
the rail which they can directly read from the schematic rather than
forcing them to do the calcualtion?  That seems a bit clearer and more
user friendly (plus if someone decides the spec was wrong it's easier to
roll out fixes).
