4 Years of Whaling on JP Proseka - What Does My Account Look Like? (PJSK/プロセカ)

Several people have asked for details about my account throughout the years, like how many 4-stars I have, how much have I spent, etc.
Since the 4th anniversary just passed, I thought it would be a good time to showcase my account and total up all my resources and spendings.
If you have any question that I didn't cover, let me know and I'll try to answer it.
Maybe I'll do an update every year and answer frequently asked questions.
A copy of the Google Sheets with all my 4-stars on it (won't be getting updated):
