Support for SermonSpeaker 4.x is canceled as it is for Joomla 2.5. I will gladly assist you with minor issues but I will not fix any bugs anymore in this releases.
The fix is to upgrade to SermonSpeaker 5.x and Joomla 3.x, which is better anyway.
It's a simple counter which counts every pageview.
However you can specify some usergroups which are not counted (like Super Administrators) in the SermonSpeaker Settings -> Permissions. So you could exclude your own hits to be a bit more accurate.
