Please don't take that as being said in a condesending tone. It isn't mean that way. But I do not see your data rising to the level of Welti's, in fact, I do not see any data from you at all. What I would prefer to see, is a study of a large number of random setups that showed the energy distributions in each. That way it could be determined how reliable this approach is over a number of different iterations, different rooms, different random setups, etc.
