Which of you do say true? Rubbish of good projection?
A projection is not a map of a flat earth. A projection does not have a scale that is the same everywhere. A projection can be a good projection because it is good at being a projection. That does not make it a good flat earth map.
A flat earth map on a sheet of paper has to have the same scale everywhere. Projections do not have a constant distance scale. There is no such map of a flat earth because it is impossible. All maps claiming to be flat earth maps are rubbish. Flat earth "maps" made from using airline flight times are the worst rubbish of all.
