Anyone have experience installing Hughes cams?

I’ll pre-game my question by saying yes, I know how to and that I should degree all camshafts. I also have the tools required to do that. I’m just looking for an explanation as to how Hughes specs their cams and how they write their cam cards. I contacted their tech line and was giving a “don’t bother us” answer of “it’s on the spec card”.
Here is the cam card below:
My question is about the installed centerline.
Do they mean that they grind it on 109° and I’M supposed to manually advance it 5° via a multi key crank sprocket to 104°?
OR
Do they mean that they already grind the 5° into the cam and if you line it up “dot to dot” (and everything else is correct) it will already be at 104°?
The reason I’m asking is that (usually) these specs are in 2° increments. A 9 slot sprocket is in 2° steps... but they want 5°?
That’s why I’m questioning this. If I have to manually advance it I’d have to use the 6° key way and end up at 103° (again assuming everything else is correct).

Any thought are appreciated. Thanks!

Haven’t personally used Hughes but can advise that cam industry practice is to supply the cam so as that when installed dot to dot (given everything else is correct) the advertised centrelines will be achieved.
