This video really talks about how we try to avoid the obvious, yet correct answer of the FASTEST way to improve your aim in any shooter. People tend to skirt around the question and try to avoid doing the task altogether.
This is normal, however, so, understand that doing Kovaaks/Aim duels/Aim maps is like any other hard task that requires long-term consistency to see results.
You will not gain muscle mass without going to the gym. You will not get significantly better aim without aim training. That's it. Nothing more.
