Reading it twice and sitting on it, I have an uneasy feeling.

It feels like it distracts more than it illuminates. ex. Quasar Equation. I don't know what it capital-M Means that at (X, Y) = 0, there's a region where there's higher differences between y and x/x^2+y^2.

But counterpoint to myself:

I'm looking at a toy example.

I'm sure there's been plenty of times I was genuinely comparing two equations and needed to understand where there'd differ.

Its just harder for me to grok when one of the equations is "y".
