How best to use directed comma names

[Moderator note: This post (and the following 8 posts) were moved from the topic "Extending Trojan notation to finer resolution" where they followed this post.]
Surely is simply 1/5C and is 5C. Or is it 5/1C? In the case of being 11C, is that directed or undirected notation. There's no comma or slash. Are we now forced to write 1:11C for undirected? I want the new kid on the block to accomodate the old guy. (and I'm not referring to you and me). In the old undirected way we would write:
= 5C up
= 5C down
So I think, in the new directed way, we should write:
= 1/5C
= 5/1C
And hence, I think the apotome should be:
= 3/1A
= 1/3A
Perhaps reread Juhani's criticism here:

But this time with the benefit of knowing in advance, that he does not read ":" as undirected, but as being exactly the same as "/".
No. Nothing better. Unless I realise soon enough that I can just hit my browser's Back button to recover the original.cmloegcmluin wrote: ↑Fri Jun 19, 2020 5:51 am I forget — do you have a better way of getting my previous post back besides using ChromeCacheView or the like?
If you need to follow the comma name with "up" or "down" then in what sense is the name itself directed?My first reaction was "ah, yes, great point... 1's reciprocal is itself, so we can't effectively indicate what its inversion would be; the 1/1A is the same thing, but 1/3A is different from the 3A."Dave Keenan wrote:I think the apotome should be called "3A". If is 1A, what is ?
But then I realized: wait, wouldn't just be a 1A down? Just as is a 1/5C up and is a 1/5C down?
