Okay I am happy to help you understand if I can Basically whenever there s a statement like for example is widely considered a delicacy or was regarded as his greatest failure success or anything like that it s a good idea to show an inline citation to make it clear that the point of view being discussed is verifiable and is not just the editor s own POV or own conclusion I m not sure where this is explained in the MOS or similar documents but after a time you ll probably come to instantly recognize where these are needed Happy editing
