That was only as used as a reference, when we know exactly what the surface was, and it's the same for the events that were listed previously.
When putting the "Indoor" category I was referring to the ordinary ATP Tour events, especially those we were discussing about, ISG.
You consider indoors to specifc, but the actual surface of indoors doesn't exist. Therefore if there were carpet or events on wood, then they'd be refered to as that.
The indoor/outdoor clay example, one was played outdoors and one played indoors, that is the difference and not the actual playing surface. If indoors is a specific surface, then please explain how that is? A hardcourt, grass, carpet and clay are seperate surfaces with or without a roof.
