TAOW3 supply questions

[flip0009]

I have read that article and I found it very informative.

However, like I said, I cannot find a definition of how the supply numbers apply to resupply of a unit. For example, If I have a unit on a 36 hex, does that mean it has a 36 percent chance of resupply or does the number mean something else? Or, if I have a unit in need of supply on a 36 hex along with it's HQ unit what does that number mean? Or does it change the number? Do the numbers only apply to HQ units and normal resupply for the rest of the formation? If I have a supply unit, how do I position it for maximum supply? How does a supply unit effect the supply number or does it?

I get the basics, HQ supply units best if not moving and near, but I wonder exactly how to do this the best way.
