Maybe I missed it, but I could not find any clarification as to what this represents? There are slides and there are scenes. Where is the "section" coming from? As far as I can tell, the number only increments on standalone scenes. example: If I have 4 linear scenes, this variable will return 1 through 4 respectively. however if I have a scene (parent)that branches to other scenes (children) using buttons, those "children" scenes will all return 1 in the variable.
