Google Maps JavaScript API - Automate Zoom Level?

Question

I'm working with multiple map markers. Currently I use map.fitBounds(bounds); in my JavaScript to resize the map. bounds contains multiple LatLng objects.

What am i doing wrong? Because it zooms out too far :-(

JavaScript source

var geocoder, map;
$(document).ready(function(){
    var coll_gmap = $(".gmap");
    if ( coll_gmap.length != 0 )
    {
        //initiate map
        geocoder = new google.maps.Geocoder();
        var latlng = new google.maps.LatLng(-34.397, 150.644);
        var myOptions = {
            zoom: 13,
            center: latlng,
           mapTypeControl: true,
            navigationControl: true,
            scaleControl: true,
            navigationControlOptions: {style: google.maps.NavigationControlStyle.ZOOM_PAN},
            mapTypeId: google.maps.MapTypeId.ROADMAP
        }
        var bounds = new google.maps.LatLngBounds();
        //loop all addressen + insert into map
          map = new google.maps.Map(coll_gmap[0], myOptions);
        coll_gmap.each(function(index)
        {
             if (geocoder) {
                    geocoder.geocode( { 'address': $(this).attr("address")}, function(results, status) {
                        if (status == google.maps.GeocoderStatus.OK) {
                            map.setCenter(results[0].geometry.location);
                            bounds.extend(results[0].geometry.location);

                            var marker = new google.maps.Marker({
                                map: map, 
                                position: results[0].geometry.location
                            });
                        } else {
                            console.log("Geocode was not successful for the following reason: " + status);
                        }//end if status
                    }); //end if geocoder.geocode
                } //end if geocoder   

        }) //end coll_gmap each
        map.fitBounds(bounds);

        }//end if coll_gmap length
       /* console.log("Script created by NicoJuicy");*/   
}); //end onload

<div class="gmap" address="SomeAddress1" style="width:700px;height:350px"></div>
<div class="gmap" address="someAddress2"></div>

I have found the solution.

Instead of doing a single

bounds.extend(myLatLng)

Everytime you add a myLatLng to your bounds, do these actions

bounds = map.getBounds();
bounds.extend(results[0].geometry.location);
map.fitBounds(bounds);

Hope this helps anyone!
