Opportunity = trend 0.0 × (1 − saturation 35%) × stage weight 0.4 × niche relevance 1 = 0.0

Saturation parts: volume 71%, time elevated 0%, mainstream 0%. Spike ratio = mean of the last 3 days ÷ median of days 4–31. A source counts as spiking at ≥ 1.5× and robust z ≥ 2.

Full method: methodology. Rising means rising now; it is not a prediction that a topic will go viral.
