(meteorobs) showers shifting through time

I know little about Computing Meteor Activity based on their occurrence
patterns. However, that said, the orbits of high speed objects like that of
Comets, Planets, and Moons in any Solar System, are governed by Harmonic
Orbital Mechanics. If the timing of a shower somehow slightly changes a few
hours over many years, it is no doubt from precession in the rotation of the
Earth in relation to the Orbital position of the Earth, not from a shift in
the orbit of the debris field left behind by the responsible Comet.

Long ago I was taught that the Leonid meteor shower shifts in time and
occurs about one day later for every 71 years that passes. But is it correct
that not all showers gradually shift according to such a pattern? Do all
showers occur at the same time according to the tropical year, or do some
have a different rate of shift?
