Derek Hough pulls away from the rest of Maksim Chmerkovskiy's top 10 at 0.88 — a gap of more than six points over the next closest neighbor, making this a textbook spike structure.
The shape is concentrated but not narrow in kind. Three of the top 10 neighbors are TV Personalities — Derek Hough (0.88), Jenny McCarthy (0.82), and Howie Mandel (0.78) — matching Chmerkovskiy's own subcategory. Dancing with the Stars, a TV Show at 0.80, sits directly between those two clusters and is the only show in the top 10 that shares the same competitive-dance context. The remaining six neighbors split across Actors — Michael Weatherly (0.79), Jeffrey Dean Morgan (0.79), Donnie Wahlberg (0.78) — and one TV Show, Castle (0.77). Bon Jovi (0.77) is the lone Musicians and Bands entry in the top 10, and Norman Reedus (0.76) rounds out the actor cluster. The actor and TV-show neighbors skew toward network procedurals and ensemble casts rather than anything dance-adjacent, which means the audience overlap is driven by shared viewer demographics rather than shared subject matter.
The spike on Derek Hough, combined with a supporting cast of network-TV actors and personalities, points to an audience shaped primarily by mainstream American broadcast television fandom.
