Lol. I failed math in high school. I’m still having trouble seeing what you think is so concerning.
My wife has trouble with math (not that I’m a whiz). :-)
It’s not so much a concern, but it has my curiosity peaked, because I don’t remember seeing this in any other poll.
Basically what it means is that when one goes up by x the other one goes down by x or close to x. Think of it as 2 dancers mirroring their moves. When they step back, they move apart; when they step forward, they move back together at the place they started, or near it if they didn’t quite perfectly match each other’s moves. That’s what I see when I look at the chart and do the math. The place they meet is around 43.5 to 44.5, going back to July. I would think that the place they meet would move more than that over 3 months time.
