That is a great question. There is a formula for it that I do not recall but you should be able to find it. I will have a look as well when I have a second and let you know.

Well said but how does it impact the timers, I mean based on what criteria? If I have five switches A,B,C, D & E, where A is the root and B & C are connected directly to it, whereas D is connected to B and E is connected to C, finally D & E has a connection between them. In such a scenario if we set the diameter to 3, how will the timers be readjusted for optimization?
