Theres an actual continum that is ancienet. East AFricans are not separate from other Africans per se. Atleast in terms of superficial blackness. If you have lets say 2% East African from Polako or Mcdonald this is using Masai reference samples, and the Masai are one of the oldest and blackest people in Africa, they are very dark skinned and have tight hair. But are distinct enough genetically to make a difference in the African scores of ethiopians when they are included or excluded. You for example having East African is not direct but rather through the west African. So lets say 3k Years ago a band of Proto-Masai people left East africa and ended up in chad, and then 1k later ended up in Senegal or North Nigeria. This is how u would have gotten your "masai" by a rather indirect source. There are quite a few west africans with east african migration stories while some are localized. Son in this DNA test id' suggest you combined the east and west african as "black" vs separating them. But when you are doing intra-african analysis on yourself u wana separate em to get an idea of what your African ancestry is composed of. The only ones that are tricky are Mozabites because they have elements presetn in both south euroepans from admixture with them as well as Admixture with sub-saharan africans, so even "north african" scores from mcdonald have significant sub-saharan so some of that score is real sub-saharan, some is real south european and some is real north african.
