I am not asking this question as a Love For CP forget about rating point view.

I was just curious about how much effort it takes to reach a particular rating.

Is it equivalent to how many questions you have solved?

I have seen people doing CP continuously for more than 2 years. Continuously practicing, up solving, have solved 1000-1500 problems significantly of good ratings but still, they are stuck between 1400-1500 ratings.

And also there are many who are doing CP for the last 5-6 months reaching 1600+ ratings and all.

Just want to know what are the other factors than practice on which problem-solving abilities/ CP ratings depend?
