That sounds about right. Of the 54 comets I have seen, 13 have been naked-eye.

                      Bennett - Spring 1970 - naked-eye  1st magn.
                     Kohoutek - Winter 1974 - naked-eye  3rd magn.
       Kobayashi-Burger-Milon - Summer 1975 - naked-eye  4.5 magn.
                         West - Spring 1976 - naked-eye   0  magn.
            IRAS-Iraki-Alcock - Spring 1983 - naked-eye  1.5 magn.
                       Halley - Spring 1986 - naked-eye  3.5 magn.
                    Bradfield -   Fall 1987 - naked-eye  4.5 magn.
           Aarseth-Brewington -   Fall 1989 - naked-eye  3.5 magn.
                       Austin - Spring 1990 - naked-eye  4.5 magn.
                    Hyakutake - Spring 1996 - naked-eye -0.5 magn.
