Oh dear... but I think the FamilySearch comparison must, because of its nature, rely on aspects of resemblance that can be reduced to mathematics - ratios of distances between facial features, or perhaps equivalent things that can be drawn out of the data using AI. It can't really capture the less concrete aspects of resemblance - mannerisms, for example, and even things like eye/hair colour since most of the photos it's working with are black and white. So perhaps the resemblances that a human observer might pick up on and the ones that the algorithm picks up on are quite different from one another.
I've also come across resemblances in the 30% and 40% range between people who are, as far as I'm aware, unrelated, as well as between people who have a grandparent/grandchild relationship. I suppose a lot does depend on which features you inherit from which ancestors too.
