Would there be any data out there on what fraction from this 60ms to 80ms RTT is raw propagation delay and what fraction is typical packet queuing delay at intermediate switches? Does queuing delay play much of a role at all these days? Or is it all just propagation delay?
Measure the distance, figure the signal is moving at 60% of the speed of light, and anything over that is queueing/switching delay. This of course assumes that you have some idea how the cable runs....
