Your descriptions of mapweight in the FTP README for Chromosome Reports and for SNPMapInfo in the data dictionary are contradictory. Which is correct?

The mapweight definitions for the database are different for historical reasons, so both definition series are correct: The mapweights defined in the chromosome reports section of the FTP README are true for chromosome reports, and the definitions given for the database tables in the database dictionary are true for all FTP data table files.
