#2 Not aim training enough
The second reason you may not be improving your aim is because you simply are not training your aim enough. Here’s a guide on how to aim train. The amount of time required for you to train your aim is different person to person because it depends on how many total hours you’ve played of FPS games and many other factors. If you have been on the same settings and sensitivity for years then you may find that you don’t need to train your aim that much. However, if you haven’t been consistent with your settings for long periods of time then you might have to train your aim more.
If you don’t have a lot of hours to play games everyday then you should focus more attention into training your aim. You can train your aim for as much as 2-3 hours a day with sufficient breaks if you really want to improve your aim. Training your aim for only 20minutes a day won’t improve your aim for most people especially if you are doing other factors that decrease your aim comfort such as playing other games or not training everyday.
The bottom line is if you don’t have a lot of hours, don’t play everyday, don’t aim train everyday, don’t have a lot of previous FPS experience or don’t have consistent settings then you must double how long you train your aim for if you want to see improvement.
