What berries does this little faggot need?

Ive I google the question or any variation I get 5 line "articles" by video game "journalists" saying to evolve feebas you need to raise its beauty, blue berries such as oran work best

and I cooked all my oran berries perfectly, maxed out its sheen and its too low still, like what level of dry poffin do I need? or total beauty max? is there a number
