So in last couple days I have been observing some players from top of the ladder. Many people are sometimes amazed by their high APM. I can tell you, it is a complete missinterpretation of the skill. But on quite some serious level imo! Some common things I have noticed, that influence APM a lot: They never use continuous build and always click their queue. They ussually do a mix of units and then shift click (with mod) couple hundred units. This adds quite a lot to your APM. They manually queue the mex in the beginning and even later in the game. Compare those 5+ clicks to a click&drag area command, which is a single action. They mostly always triple or more click for units to move to the same location. Doing this all the time can improve your APM significantly. Same like mex, they tend to place energy by clicking. Some even don't spread it so there is really no point not to use a line command. (Some of course spread it quite a bit and that is understandable and desired). Spam clicking. Everywhere and all the time! When doing this, your APM is often 150+ or even higher, 180+. Compared to a player with 80-100 steady APM, who doesn't do anything mentioned above, there is basically no difference. Trust me Their skill is mostly in very good map awareness, working very efficiently with their fabricators and spreading over the map quickly. Also they manage well their expansions and surround you nicely. These are the differences between you and them, not their APM. So don't be scared that your APM "sucks". It is just fine as long as it is above 80+ and is steady. Try to focus on other skills, don't try to improve your APM but your tactics.
