Yes, it does. But it requires you to look at the equation and understand
it, rather than just memorizing tidbits. Look at the snippit surrounding
K2.
(K2 * Bandwidth)/(256-load)
If K2 is 0 ..... then outcome of that equation will always be ZERO (in
fractions .... zero over anything is always zero), which means that the
load value is never considered. A Non-Zero value means the outcome will
not be NON-ZERO, thus making a difference.

load. I need something like this: K1 - Bandwidth
K2 - LoadK3 - DelayK4 - ReliabilityK5 - MTU I'm not sure if the above
values are correct but I would like to have something along those
lines.

Set K2 to 1 if you want it to consider load.

Metric = [K1 * Bandwidth + (K2 * Bandwidth)/(256-load) +
K3*Delay] *
[K5/(reliability + K4)]
The default constant values are K1 = K3 = 1 and K2 = K4 = K5 = 0.
