Can somebody give me some insides to that Propagation-Rate and Half Life Settings?

I understand that those values are helping to travel the impact data through the Glue Network, but I don't understand why more propagation keeps the network stiffer - and I have had not much luck in changing the values and get a significant impact on my constraint network - but nothing is unimportant in Houdini, so what is it really doing and are those values some kind of RealWorld units ?

And Half Life, yes it decays the impuls by half…. but how does it interact with the Propagation Rate…
