Percentage in Title
Whether the title contains a percentage (e.g. '40%', '80 percent'). A data point rendered as a number carries more authority and specificity than a vague framing.
Percentages anchor claims in data. '80% of voters agree' reads as concrete and verifiable; 'most voters agree' reads as an opinion. Titles with percentages tend to signal research-backed or poll-driven content, which rewards the political YouTube audience that came for substance.
Average Video is the effect on a typical video. Top 10% Video is the effect on the videos that broke out (top decile of views) — so you can see whether a factor helps most videos a little, or pushes the top performers much higher.
