@awulkiew Andoyer was selected as a good balance between accuracy and speed. So it is quite fast and still (reasonably) precise (but of course not as precise as Vincenty).

@cffk I just answered why it was chosen as the default. Of course it completely depends on the application. If you compare it with haversine it is much much better,...

(Oops, sorry for the click on the wrong milestone )

Thanks for the report. As far as I know, for within calculations rescaling is not used? Then it might be influenced by my recent changes indeed. It might be that...
