I will try to describe the initial system and then ask the question.
You have a substance that has 10 different characteristics. You have lots of data and some of your data seems to be high prediction accuracy. I think if I only use factor A data, the results of factor B can be determined, but without the elimination of factors C D and E the extra data of ACDE confuses the results when determining factor B.
Does this make sense to anyone but me??
ps: You blew my mind, my time to blow yours….
I have no idea, sorry…
