Yes, this is the point I've been trying to make, subtly, but failing :-) In the second terminal output box in your article, you are checking R7's s0/0/0 interface, but the bandwidth and delay values specified there are irrelevant. Nice article, but if I could give one piece of feedback it would be to make it painfully clear that the composite metric is calculated "uni-directionally" -- from the device performing the calculation, to the ultimate destination -- using the egress interfaces *only*, including the ultimate directly connected interface, in each hop along the path. (in this case, R8's s0/0/0 and R7's lo0.) I've found this fact to result in a 'light bulb moment' for lots of people struggling with EIGRP metric calculation.
