Soren,
that's the thing. Science has to admit that their "one way view" on statistic's is not applicable for "system evaluation". I'm not in statistics but a good statistic Prof. explained to me that when you have a group which is under the influence of many variables you can get still statistical relevance without replications through time.
Anyway, for me most interesting was that in Precision Farming they use this "Kriging" http://en.wikipedia.org/wiki/Kriging for creating the yield- & other maps. He said that this statistical procedure is not appropriate for this data bases as there are tooo many moving variables. but still it's used and generally accepted. this Prof. is one of the leading proponents of PF in the PF world.
So in the end the scientific world is still using a unsuited formula as they don't have s. thing better and none is questioning the results. The Prof. also shopped me how to do multi results, totally different looking maps from the same data set. Now every one who has a program can play with the data. And who is saying what is right a& wrong? My conclusion, after working with the PF pioneers for many years, is that in most cases the farmers bottom is the best Precision Farming map. ;-)
