Now i am stuck, could you please read the question i quoted from you 
above again and tell me if i answered your question or not?  If not 
please specify what is missing.

I have the impression that when you don't like the answer you get you 
simply say that's not what you are trying to do, that you don't want to 
simulate reality at all - fine, but then why do you ask the question in 
the first place?

I did not talk about impacts in my answer at all.
