> The OPs seems to be more cumulative lifetime stats rather than just this past year, for a lot of the slides.

I disclose that the last 5 slides are lifetime stats in my readme:

"Note: The last 5 slides are not necessarily specific to 2025 because of leetcode's graphql api only allows querying up to 20 of the latest submissions from an unauthenticated user.

However, if you pass a LEETCODE_SESSION cookie (obtained from leetcode.com, open dev tools -> application -> cookies) with your request you can query all of your accounts submissions. You could also use the calendar endpoint query all of your submissions in the past year, and thus create a much more nuanced leetcode wrapped. (ex: You struggled with this problem the most in 2025.)"

I may try to tackle this via an extension with no server side logic if I have some free time later this week, would certainly be a cooler final product. Only caveat is users would have to manually install the extension from a github repo (too scary for most people) or the chrome web store, which may add too much friction for most people.
