It is not obvious. But has come up in discussions with the Google
Engineers that frequent this group.

I found that I needed two flags. It seems like it is 48 first then
12, so it takes a couple of zoom change events to get it right.
I did something like this:
google.maps.event.addListener(map, "zoom_changed", function() {
var desiredZoom = 12;
if (initializing && (map.getZoom() == desiredZoom)) {
initializing = false;
} else if (initializing && (map.getZoom() > desiredZoom)) {
map.setZoom(desiredZoom);
}
});
