After today, I think I will be paying more attention to the "Scores". I was initially confused by why a profile should have a Quality Score of "Low" when I had completed the Vitals and attached birth, death and census sources. I then realised I had not removed tagged Events that I had previously attached to him (died in infancy) after attaching sources for events that took place after his death and transpired to relate to his later-born sibling, of the exact same name.

It is so easy to leave these Events (under "Other Information") when detaching the matching sources, so I'm grateful for the DQS feature in this instance for pointing me to my careless lack of attention to sloppy work (attaching sources that could not possibly apply to that individual and then forgetting to remove the items under Other Information when I realised my mistakes).
