Slight zoom on MKCoordinateRegion?
I am zooming an MKMapView to fit the bounding region of a collection of pins, however when the pins are displayed I have noticed that the zoom could ideally do with being a little tighter. My proposed solution to this was to make the region deltas slightly smaller:

    // SMALL ZOOM
    locationSpan.latitudeDelta = (locationSpan.latitudeDelta / 100.0) * 97.5;
    locationSpan.longitudeDelta = (locationSpan.longitudeDelta / 100.0) * 97.5;

However I have noticed that fine adjustments don't seem to translate to a small zoom increase, is there some form of snapping on the zoom? Really small values work, as do really big ones, but just adjusting the region size by a few percent does not seem to work with the view nearly always jumping/zooming in to far and clipping my pins.

    // REALLY WIDE
    locationSpan.latitudeDelta = (locationSpan.latitudeDelta / 100.0) * 250.0;
    locationSpan.longitudeDelta = (locationSpan.longitudeDelta / 100.0) * 250.0;
    
    // REALLY CLOSE
    locationSpan.latitudeDelta = (locationSpan.latitudeDelta / 100.0) * 10.0;
    locationSpan.longitudeDelta = (locationSpan.longitudeDelta / 100.0) * 10.0;
