I hear you. Usually the bottleneck of macro-effectiveness is the part you mention, the decision-making parts can be simplistic in mid-to-high levels and still plenty effective. So "improving your macro" usually refers to remembering to build workers and not getting supply blocked. Getting supply blocked or not hitting production cycles is more likely to get you behind in StarCraft.

That said, in high-level play, "better macro" usually refers to the other things, not just mechanically hitting stride with production, as most players in the top .01% are on the same level with those mechanics.
