The instantaneous age increment of the mid cell (position=50) of CA-1 and CA-2 was added respectively to the mid cell age of CA-3 (marked by horizontal arrows). This addition accelerates aging of the mid cell. The graph below depicts the age of the mid cell under the control of CA-1. At t = 48 it reaches max age, its age is set to 0 (white), and remains so.
Under the control of CA-2, CA3 ages faster. CA-3 mid cell age reaches the max age at t = 2 its age is set to zero (white) and remains so. The entire mid cell line (position = 50) is white. In the last example CA-2 control of CA-3 is slackened. Only 0.8 of the CA-2 age increment is added to the CA-3 mid cell. Now aging proceeds at the same rate as in CA-1. We may thus conclude that CA-2 is about 1.25 (1 / 0.8) times older than CA-1.
