The determination of the latitude says something about the angle in which the map should be "round" at a certain latitude value. The curvature of the world at this latitude.
The map is OK, it's a proper projection on flat screen. If you connect some points, they are exactly on a given meridian as they should, but the whole map should be about 50% width! The explanation why is in post #15 and the above formula.
