Convoy Generation

This is basically a rules question, so I don't know if it belongs here. What is the chance that a convoy will appear every 4th turn - 80%, 90%? I know the actual strength of the convoy is partly random, but what about the chance of it actually appearing on the map.

It is like, if convoy has value <10 then it does not get created.
