It should not occur if you had two the same tests. Right now you have a test of going from a cablemodem to an analogue modem and a test of going from an analogue modem to a cable modem. Anyway, the thing you see is that the serialisation delay of an analogue modem is much higher than that of a cablemodem. If you reduce the speed of your cablemodem back to the speed of the analogue modem, you will see it has the same values.
