Wow... that sounds really awesome! I wouldn't be able to estimate in such a manner. I heard of such softwares in the market but not all of them are accurate. Probably the really good ones would be used by the government.
I used to roleplay for a while and I thought that instead of wasting time by just roleplaying I made these compilations from the game I played (and roleplayed).
It was great fun and I almost landed working along with this game co to design clothes (for free, for the sake of the fans) before they were abruptly discontinued due to change of management.
