When I wrote 'articulate.ly' lilypond's handling of Midi grace notes was rudimentary at best. It's changed since, and may now be fighting with what articulate does. I was mostly interested (at the time) in Baroque music practice, and was following CPE Bach, 'The True Art of playing Keyboard Instruments'. In chapter 2, 'Embellishments' section 2 'The Appoggiatura', point 11 he says, 'The usual rule of duration for appogiaturas is that they take from the following tone of duple length one half of its value, and two-thirds from one of triple length'. He also says in his next point, 'appoggiaturas which depart from this rule of duration should be written as large notes' And has a heap of counter examples -- for instance, the performer ought to be sensitive to what else is going on to avoid infelicitous clashes with other parts, or successive open fifths, or ... and goes on for a whole chapter.
