In NR 1.2.3, Upbeats:

So \partial 8 becomes:
\time 3/4
\set Timing.measurePosition = #(ly:make-moment -1 8)
e8 | a4 c8 b c4 |
_The property measurePosition contains a rational number indicating how
much of the measure has passed at this point_. Note that this is set to
a negative number by the \partial command: i.e., \partial 4 is
internally translated to -4, meaning “there is a quarter note left in
the measure.”
"""
IMO the first sentence is a bit confusing.
I agree about confusion, but not in the first sentence, but in the last:
-4 actually means "it needs one quarter note until the measure even
starts". (\partial inserts a partial measure 0 before the measure 1, and
measure 1 is the first measure where counting starts)
Cheers,
