I pulled FE map from this site and attached an example of why the FE map simply doesn't work.  Basically a flight to JNB to NBO is 4 hours and a flight from JNB to SYD is 12 hours (3x).  Yet the distance from JNB to SYD is at least 7x as long per the FE map.  The flight route to Sydney would actually be much longer as we know flights from South Africa to Sydney go over the ocean (not Asia).  Sorry about image quality (limited by Forum).
