How these totals are calculated

The total is the sum of the General Payments records CMS published for the labeled program year(s), exactly as published. Nothing is estimated, weighted, or combined across categories.
General Payments only. Research and Ownership/Investment are separate datasets and are never summed with these figures; amounts are kept separate per program year.
Featured-page threshold (a presentation gate, not a judgment): records>=3 OR total>=100 (all years).
