This is from ncaa.com: "With the changes announced in May 2020, the NET will no longer use winning percentage, adjusted winning percentage and scoring margin. The change was made after the committee consulted with Google Cloud Professional Services, which worked with the NCAA to develop the original NET."It’s not true. Wins/losses layer in on top of the efficiency stats. But we don’t know how large the adjustment is for wins/losses and to what it’s applied. And the lack of transparency around that causes fans to lose our collective minds.
You are correct that no one knows the NET formula, which is completely maddening since it has become so important for tournament decisions.
