I have an issue with 3. It very much depends on the data set and what is actually being portrayed/the context. Who is to say that 6 years is enough vs 2? We need to know a lot more in order to say xyz is bad because it’s 3 years.

Not sure how old beer bread is, but I grew up with it after my parents bought a community cook book. Lots of Mainers seem to make beer bread but nobody I know from out of state has heard of it. You might also want to look into Marge Standish and her books. Again, I’m not sure if it’s 200 years old, but her stuff is very Maine.
