1- v/c is actually just a number.

Actually, random behaviour is quite common in the real world.

Many things behave in unpredictable ways, hence are certainly modelled 
with random numbers. (at least they should be).

I have doubts.

Human nature is often only half-concess.

If coherence is introduced by force, we had a guarantee, that things go 
wrong.
