I've had big salary bumps before. My experience was that I made more money and could afford to invest more and buy more stuff with it. What did you expect?
Not the experience after you got the bump. The experience of getting that 200k it cud be because of switch from one state to another or may be because you specialized in some specific tech.
The purpose is to identify what really led to a 100 % bump , i believe it is not something that happens usually in many cases and few special cases might have led to this.
To understand wat paved the way for this special case to happen.
The most common way to do such a thing that I am aware of is to move from a small company to a FAANG company, especially when that involves moving to Silicon Valley from somewhere else.
Moving from academia to industry can also result in a large pay increase.
