Again, no. If you look at just x without the context of y, all you see is a line. If you look at y without the context of x, all you see again is a line. It isn’t until you realize both x and y are free variables that you understand what you’re actually looking at is an equation for a plane. Looking at one variable alone gives you a single slice, when there are infinitely many slices. If you wanted to integrate that function, it would be a double nested integral, not two separate integrals that you add together individually.
The matchmaker is no different. Like I said, the matchmaker could put teams together with absolutely no spread, but if the MMR value is inaccurate, there still a spread in reality. Ergo, the system is flawed.
Likewise, MMR could be accurate, but if the matchmaker creates a spread, it still results in an unbalanced match.
The two variables are codependent, you cannot just analyze one without the context of the other.
