Let's say we have a perlin noise set with the default scale of 250, let's call the top row of pixels of this noise function a wave "x".

Let's say we have another perlin noise node. The scale of this perlin noise is not determined yet. Let's call the top row of pixels of this noise function a wave "y". What scale setting do we assign to this second perlin noise in order that the frequency of the "y" wave is 4x the frequency of "x"?

I guess I don't really understand noise scale at all.

I actually have no idea. So I would suggest that you make them initially both scale "y" and then size the other one up by profile gradients to 4X (to scale "x"). That way you know they are to scale. Unless someone knows how exactly how the noise scaling works.
