Hi Cynthia, Hi Jay,

A little off-topic :

\version "2.19.15"

\markup\italic "I'd right it so:"

\score {
  <<
  \new Staff \relative c'' {
    #(define afterGraceFraction (cons 15 16))
    d1~\afterGrace
    d1\startTrillSpan { c32([\stopTrillSpan d]) }
    c2 r2
  }
  \new Staff \relative c'' {
  \repeat unfold 16 d8
    d8 r8 r4 r2
  }
  >>
  \layout {}
  \midi {}
}

\markup\italic "Rather than:"

\score {
  <<
  \new Staff \relative c'' {
    #(define afterGraceFraction (cons 15 16))
    d1~\afterGrace
    d1\startTrillSpan { c32[ d]\stopTrillSpan }
    c2 r2
  }
  \new Staff \relative c'' {
  \repeat unfold 16 d8
    d8 r8 r4 r2
  }
  >>
  \layout {}
  \midi {}
}

Does anybody knows what Elaine Gould says about that?
