Only for points which are close because Pythagoras only works accurately on
planes. That's why I'm suggesting that it be defined by distances along
latitudes and longitudes.

I understand.

>We may however be able to use our current formula to improve accuracy in these

If so, that'd be cool!

I appreciate it.
