Hi AKilan, The problem could be that an sphere is not an ellipsoid model, is a spherical model. So depending on where you are putting your model de preccision difference could be very large. An ellipsoid model has two radius, equatorial and polar, so defining a sphere with radius polar it's not enough to fit in a ellipsoid model. Could it be?
