More math for everyone to digest,
Surface area for the Zona Central IP anomaly is calculated to be 2,805,777 m^2 including 705,229 m^2 consisting of >18.5 milliradians.
Surface area of the Zona Sur IP anomaly is calculated to be 1,750,544 m^2, and the surface area of the Zona Incognito anomaly is calculated to be 281,959 m^2.
Adding all of these surface areas together would yield 4,838,280m^2 of earth consisting of at least >16 milliradians.
