Shared logins are not a rounding error in Malaysian homes. A teenager uses a parent’s profile because the recommendations look older. A grandparent never logs out. Kids’ titles appear on a profile that was meant for late-night drama. A household profile evening is a single sitting devoted to that traffic.
The observer notes who picks up the remote, who calls out a title from the kitchen, and whether anyone bothers with the profile screen. You receive the log and a two-page reading the next day. Many clients use this evening as a sample before they commission the full study. Others stop here, because the question was only about the account model.
We do not lecture the family about “correct” use. If they watch a horror title with the lights on and a child in the doorway, that is the record.
