vivre card is just a bunch of notes that can be right and can be wrong. Shanks being a Yonko when he met Luffy is one of the wrong notes
People should ONLY make use of Manga panels/ SBS/ and lastly a specific anime episode that was said Oda worked on supervising it! Where he wanted to add the extra details he didn't add in manga. Something like Sabo's flashback in Dressrosa being extended in anime was supervised by Oda personally. So, that's the ONLY 3 materials anyone should be taking from.
Editors notes, vivre card, databook are not trusted imo. Sometimes they give right info, sometimes they don't. It's a hit or miss
