These move in the same direction about 72% of the time
Their swing sizes only faintly mirror each other (~9% of the pattern is shared).
A faint pattern — interesting as colour, not strong enough to act on alone.
On a log scale so equal % moves take equal vertical space — best when one series has grown much faster than the other.
