Can someone please explain to me how the scorecard is calculated. Are the lines the average for that week and the big dot is the average for the current week? Or is the big dot an average of the prior weeks?

Also, I understand that the arrows are supposed to be trends, but I'm not understanding - like the below shows a downward trend but all of them are red and have the exact same score of 50, shouldn't it be a side arrow?
