Hi there, could you provide a little bit more information about your doubt? In which part of the definition are you getting this problem? I think you might actually not be wrong if you are @18:46 where Jaime makes some operations to find "Center Points" what he is actually doing is finding a point inside a surface area and making sure it doesn´t overlap with another one. So if you look closely even Jaime´s points are not at the center of their respective surfaces. So as long as your points are inside the surface and you can use them to properly display the text of the are you are not doing anything wrong .
