If you use \partial at the beginning of a score it treats the resulting
duration as the length of music preceding the first bar. This is how bar
numbering generally works for upbeats/anacrusis.

Partial expects to be given a duration. I think it will not work as you
expect if you multiply the duration by 0 (which is probably a kind of
intpu that was not anticipated). At the point when you used it it's
already effectively "between" bars and if you supply a duration it will
apply to the *next* bar, not the *previous* bar.

All of the examples of \partial in the documentation use it at the
beginning of a bar and supply the duration. If you do the same it should
work for you.
