MUIR’s nomenclature is different than what we used on MSA/TDA.
The allratings file is the same as the tab-delimited file with all 6 ratings systems, the two allmembers files are the same as the Gold Master DBF files each with 2 ratings (regular/blitz and regular/quick.) All 3 files have pretty much the same number of IDs in them,
You may need to rename them for WinTD or SwissSys, I don’t know a lot about the other pairing programs and what file names they expect to find.
At this time, automated downloads of files (once you figure out the new naming system) is not yet possible because the only download options are behind the TD portal login. I know several of the pairing program authors are working on using the public APIs to do member lookups, but these are rate-limited. Key-authenticated APIs more oriented towards TD use are on the future projects list.
The much smaller monthly supplement files are no longer being generated, insufficient demand for them.
