Neptune   17              0.0003                 0.312
but it still takes some fiddling, and so it's still a pain . . . . but at least it's possible to get things to line up using spaces rather than underlines.
Warren, thanks for your technical advice on putting tables into the message box.

I continue to stand by my argument that the frequency of our torque pulses is of no significant importance in analyzing the precessional response of a gyroscope. To repeat, for all of our readers including the OP: If I am not mistaken, the gyro does not rebound and oscillate in response to a momentary pulse. It simply nutates and precesses a small amount and then stops in a new position when the pulse subsides. A sustained series of such pulses eventually will nudge it around a complete revolution, and if the steps on the next cycle do not line up with those of the previous cycle, it is no big deal that I can see.

When I said that Venus "packs a wallop", I was only comparing it to Jupiter's component. It still is tiny compared with what the Sun and the Moon are doing all the time. I would predict only a vanishingly small amount of nutation from Venus and virtually no measurable pulsating effect from the other planets.
