200 is on the low side? I'm amateur and hit that commonly during games. I think JulyZerg was on record to hit 800 at one point. Lord only knows how that was physically possible. I would credit the source to TeamLiquid's Wiki (I believe) but I cannot search it while at work.
To avoid confusion, blizzard recently added something called EPM (effective actions per minute). Those are the one who counts. APM can be spammed or increased a lot by, for example, selecting all the larva in all your hatcheries and making units pressing one key. Pro players have a constant ~200 APM, not only for those moments.
