The idea to re-use stats with minimum changes is good. And can be applied if new stats are a failure.

I agree that Santa before he started, thought of a method to make his set. Either good or bad, he followed a direction which is good. Added to that he is putting many hours is his set. The downside of it is that to be fair, someone should understand his method and put a good amount of time to criticize.

Imho the worst scenario is when there are many sets. From start the statsmaker should be the constant, so everyone's effort could be placed in one set only.
