How do I configure text in a place marker to scale with height, so it disappears / get's smaller as you zoom out?

I have hundreds of points and all the names just overlap unless you zoom right in…

This is my KML:

<Style id="cpe">
<IconStyle id="testicon">
<color>ff00ff00</color>
<Icon>
<href>http://maps.google.com/mapfiles/kml/pal4/icon57.png</href&gt;
</Icon>
<Scale>0.5</Scale>
</IconStyle>
</Style>
<Placemark>
<name> CPE 1108ACHIMOTA_3</name>
<description>blah blah blah</description>
<LookAt>
<longitude>-0.21916</longitude>
<latitude>5.599449</latitude>
<altitude>0</altitude>
<range>00</range>
</LookAt>
<styleUrl>#cpe</styleUrl>
<Point>
<altitudeMode>relativeToGround</altitudeMode>
<coordinates>-0.21916,5.599449,0</coordinates>
</Point>
</Placemark>

it'd be within the parameters of the "Style id" or "Iconstyle id" i'd think… but I have nothing really useful that would help you be abel to get in there and therefore be able to adjust it.

as silly as it sounds, have you googled it?
