If I'm understanding correctly what you're after there's an existing
function for this. Have a look at:
https://lilypond.org/doc/v2.24/Documentation/notation/expressive-marks-as-curves#index-fall-1
As an example:

\version "2.24.2"

musicOne = \relative c'' {
    r4 c4\bendAfter #+1 r2
    r4 c4\bendAfter #-1 r2
    r4 c4\bendAfter #+2 r2
    r4 c4\bendAfter #-2 r2
}

musicTwo = \relative c'' {
    \override Score.SpacingSpanner.shortest-duration-space = #4.0
    r4 c4\bendAfter #+1 r2
    r4 c4\bendAfter #-1 r2
    r4 c4\bendAfter #+2 r2
    r4 c4\bendAfter #-2 r2
}

\score {
    \musicOne
}

\score {
    \musicTwo
}

This gives:
