This silent ugc TikTok post pulled 38M views - 554× what the account typically does (~68K views on a normal post). That gap is what Handler calls an outlier: the breakout came from the content's structure, not the account's size.

Engagement pull sits at 1/5 (0.6% weighted), measuring how hard the post moved viewers to save, share, and comment - the actions that signal real intent, weighted heaviest. The product behind it: A gamified self-care and habit-tracking app.
