All grace note after's play as an eighth note grace note after, which I presume to be 1/2 of the note before.

I'm not sure this isn't by design. After all, it's not really different from grace notes before either. But in general, it would be good to have more control over playback of grace notes. So I'm inclined to close this as a duplicate of #13811: Select playback method of Grace Notes, Arpeggio & Glissando and Articulations & Ornaments unless there is a really specific reason taken from a reputable source to illustrate why the playback should differ depending on notation for grace notes after specifically.

Sorry for the late reply, as I understand it, and unless my understanding is totally wrong, the grace notes after should play approximately something like this:

As I also understand it, the playback should be dependent on tempo, that's why each example has a different tempo. The slower the tempo, the smaller the grace note. I could be horribly mistaken - this was 40 years ago after all.
BTW, the examples are not displaying here. Display checkboxes are all checked.
EDIT: Oops! Yes they is. Gotta upload picture. Hold on to your hats!

UPDATE: I think I can safely conclude that grace notes after are really appoggiaturas of the next note. This might be because engravers would run out of room to draw a grace note, so they stuck it after the note before. So this:

actually means this:

with the grace note occurring just before the beat, not on it, taking only a small fraction away from the previous note. It is an anticipatory grace note that is unaccented, and sounds as if the instrument playing it is too early.
Here is an example which you can listen to on any recording, verifying that it is played like a fast grace note before the beat. The tempo is slow, and you will be able to note that the value of the grace note is faster than just half the value of the previous note.
