Large and sad city: = 90 Quality Years / 9 Lives Small and happy city: = 100 Quality Years / 1 Lives

Large and sad: 10 QY/L = 90 Quality Years / 9 Lives  Small and happy: 100 QY/L = 100 Quality Years / 1 Lives

 But what if someone dies?

Sad city dies in war: = (100 + 0) Quality Years / (1 + 0) Lives Sad city lives in peace: = (100 + 810) Quality Years / (1 + 9) Lives

Sad city dies: 100 QY/L (100 + 0) Quality Years / (1 + 0) Lives Sad city lives: 91 QY/L (100 + 810) Quality Years / (1 + 9) Lives
