I know this mod is not maintained anymore, but the plugin works kinda.  You are kinda stuck inside the person and can't see through them enough to see whats going on.  I couldn't find any config or data file. So I looked at the cs file.  I found this inside.
basePlayer.SetPlayerFlag(BasePlayer.PlayerFlags.ThirdPersonViewmode, true);
player.Command("camoffset 0,1.3,0");
Does this camoffset change the value of your view while in spectate mode?

The offet changes the angle of the view, yes.
