Three bad competitor choices can poison a good YouTube recommendation.

UploadPack lets you pick three channels to compare. That choice stays with you. The app now checks the quality of the comparison before trusting it. Audience overlap. Topic fit. Format. Channel scale. Publishing pattern. A 2M-subscriber entertainment channel can distort the picture for a 20k-subscriber expert channel, even when both publish on YouTube. Weak comparisons now carry less weight. Competitor research can look precise while being built on the wrong reference points. I want UploadPack to show the evidence behind a recommendation, including when the evidence is weak. Evidence before certainty.
