What I mean is, we transmit signals through wires and if we measure how long it takes from the time a signal goes into one end and comes out the other, one has a “propagation velocity” of that cable.
To picture the situation, imagine you had a pipe full of marbles form one end to the other. You force an additional marble in one end and nearly instantly, a marble is displaced at the other.
You can repeat this long enough until your first marble exits the far end if you want, but “that” time is not the propagation velocity of a signal.
