Maybe I'm totally misinterpreting, but the chart I'm looking at says "Net Win Rate of SAM Audio vs. SoTA Separation (text prompted)", so perhaps a lower number means that the alternative model is better?
Now that I go back and read it again I agree with you. Presumably "win rate" means what percent of the time did the SAM model (Meta's new one) beat the other tool over some set of examples.
