I've seen a large amount of disagreement, and very vague, though seemingly correct assertions about what I see as the five most basic and essential standards of Cuil; -∞‽, -1‽, 0‽, 1‽, and ∞‽.
My understanding would demonstrate the Cuil scale as similar to the graph y=e^(1/6x)+1 (Copy/paste into google to see graph) rotated about the X axis, to create a funnel shape.
That leaves -∞‽ as the perfect hyper-reality, where the Cuils between all things is 0; when everything is nothing.
The opposite end, ∞‽, is the perfect abstract, where the Cuils between all things is ∞; when everything is everything.
Then, simply, 0‽ is reality precisely as it is; this is intensely hard to define and in my opinion, impossible to experience as all observers have a certain difference in perception that shades their reality with Cuils. However, 0‽ can be defined as reality as it truly exists- however, it is an invisible standard, as even the most unbiased observer has bias, and cannot perceive at 0‽. This means we have to approach 0‽ from both sides, from slightly absurd and from slightly hyper real, to determine as best we can that 0‽ lies in between those two states.
-1‽ is then, the idea of things. The conceptualized perfect tree for example, whatever that may be.
1‽ is our perception of reality- trees have missing limbs, scarred trunks, torn or chewed leaves, and so on.
