Delayed Grace Notes, Double Grace Notes, and Casadhs?

Grey Larsen writes in his book about cuts on notes that descend by an interval larger than a second in the same register. In this case, he recommends cutting with the lowest finger that is covering a hole. (If going from an F# to a D, both in the low register, cut the D with the F# finger.) If you instead cut the D with the E finger, does this create what some call a delayed grace note, a double grace note(McCullough), or a casadh(Cotter)?

[nonsense]

the double cut would look like this:

xxx xoo F#
xxx xxx D/part of cut
xxx xox cut
xxx xxx

but could also look like this:

xxx xoo
xxx xxx
xox xxx
xxx xxx

… or the cut could be with any finger really.

Oh, and I wouldn’t take what Grey says as gospel.

I’m familiar with a double cut. What’s a double grace note? I’m pretty sure he doesn’t mean a double cut.

I can’t imagine what else he could mean but a double cut. Cotter’s casadh’s are double cuts, even though Larssen doesn’t understand them because he hasn’t found reference to them “in the literature.”

P.S. edited my first post to remove some of the rubbish I wrote.

I think he does mention double-cut rolls (where the first two notes of the roll are articulated with cuts), but doesn’t talk about them alone. I could be wrong tho, …working from memory.

These are a bit different. You actually cut the main note twice - rather like a cran - before playing the tap. This is not the same as what I understand by a double cut.
