What the data shows

Live analyses of MPD data · each page carries its methodology and caveats

Each analysis is its own page: one finding, the method behind it, and every caveat that comes with it. Published dates say when an analysis shipped; the numbers are computed live from the latest MPD release, so the data window on each page is what dates the figures.
