The raw data would have nothing to do with a % test. The raw data is strictly your relative matches and one has nothing to do with the other in the sense of relative matching. We each inherit our own DNA from our ancestors. I know someone who reads AI, tested several siblings and all their % are different. Some read higher AI than others because they each inherited different DNA. This is at 23andme not ancestry.
Your raw data is strictly so you can see which of your matches share DNA on same chromosome in same location. This why you can figure out if ancestry is matching you up with your matches correctly and all who share same DNA on same chromosome in same location would all share same ancestor. It wont tell you which ancestor, this is where you need to find a paper trail connecting to each other.
I have documented AI close to the living and got no Finn/Volga. Mine are close to the living and they cant read it at ancestry. Ancestry gave me a whole bunch of % that does not exist in our family at all and never did. It does show up on other utilities and Family Tree. Ancestry trying to match up matches by % will never work because the % is not reading accurately and we each inherit different DNA from our ancestors. You could have 2 siblings with one parent who is AI. One could read much higher than the other. There is also a chance one could read no AI while the other does read AI. You can not go by calculating your % according to paper.
