It's still a hardcourt, whether it's indoors or not.
Don't come with Davis Cup now. If there was regular indoor grass or indoor clay events on Tour I wouldn't have put it that way, but they don't exist and Davis Cup is not relevant for our matter here.
When putting the "Indoor" category I was referring to the ordinary ATP Tour events, especially those we were discussing about, ISG.
