Webgraber++ polling time/runs

Hi guys,

in the settings.xml there is:

<settings>
    <setting id="wgp_on_act" value="3" />
    <setting id="wgp_on_cal" value="*-*-* 03:00:00" />
</settings>

I did not find any explanation for that.

I want to change how often wg+ is running. 

On my raspberrypi, wg+ is running very very often.. I guess every hour or so..?
