What is the maximum azimuth error for the Lambert Zenithal projection?

Lambert zenithal is an azimuthal map projection centered on a point, so directions from the center are not preserved exactly across the whole map. In these projections, azimuth distortion grows with angular distance from the center, reaching its worst value at the edge of the map. For this form, the maximum deviation of the projected azimuth from the true azimuth is very small—four minutes of arc. That tiny limit explains why this projection keeps bearings nearly true near the center while never perfectly preserving azimuth everywhere. It’s much smaller than what would be implied by the larger options, and it’s not zero because, in general, a Lambert zenithal projection does not preserve azimuth everywhere.
