Both maps below show Burundi highlighted. At 3° Mercator inflates Burundi by only about 0.34%, so the two maps largely agree on it. Watch what the old map does to Zambia beside it. That contrast is why the new world map matters.
At 3°, Burundi sits in the band the old map drew almost honestly. It is one of the regions Mercator quietly under-represented, and that is exactly what the new Equal Earth map restores.
