I made this! To address the valid concerns of @Asashosakari; maintaining data integrity was not a serious concern for me when making the site due to 1. no one using the site other than me, 2. having sumodb as a solid reference to be able to correct mistakes later and 3. I am making a system to allow anyone to contribute edits to the database (after verification).
At the moment, I am just testing out fun ideas and designs to try to effectively communicate the data.
Thanks for pointing out those issues and I will try to correct them quickly. I definitely released the site too early but I would've have missed a lot of these things without someone pointing them out to me. I hope in a couple of months it will be more solid and inspire a little more confidence. I would love to hear more feedback and ideas. Apologises for the bugs/mistakes.
