Here is my basic understanding of scoring "buckets." FICO has approx 12, which are actually different scoring algorithms. The criteria for algorithm categorization is a FICO trade secret, and you will never find a specific definition anywhere, so we can just read and speculate.
It is my understanding that a first major cut is made based on the presence or absence of major derogs in your file, which places you into a either a "clean" or "dirty" file categorization. I say this based on reading of many credit scoring publications on the market. That seems to be the first major divison in most published credit scoring models. There are then apparently sub-buckets under major buckets, such as lenght of credit history, but when still in the dirty bucket category, changes are not significant for other factors, such as length of credit history, as observed by Hauling.
But for those with a "clean" file, the sub-affects of credit history, inquiries, etc, may have a more significant affect within their category.
That is my understanding.
