I’m on the side of keep things simple, we already have enough issues with P0-5, let alone any more than than that. The issues are only exacerbated when I forget that people outside this community might not know the positions / what the hell I am on about (e.g. the biohack.me forums when they used to be active, or their slack group)
Personally, if it’s something that has to be studied / decoded, there’s little point, use some other description or a diagram 
. Lots of us have said hold on a moment, I’ll draw a picture before.
