Known size sums only the rows where AUM was obtainable, so treat it as a floor. Yields are on different bases: some are 7-day trailing, some are 30-day, some are the issuer's own displayed number, some are a supply APR that moves every block. Each row states its basis. Comparing them without reading the basis is how people get this wrong.
