Find the most suitable zoom level to cover a set of points without changing the map

Hi,

I can assume what you're going to tell me: use SetMapView() as answered in many threads like these:

The problem is that SetMapView() effectively changes the map to contain all locations.

I am interested to find the most suitable zoom level to cover a set of points without changing the displayed map.

I need one number only: the correct zoom level !

Thank you very much.
