 "note": "Re-cut of the September 2026 benchmark sample (58 creators surfaced by TikTok search in six niches, their 10 most recent posts each) to measure how much plays swing from post to post within one account. For each creator we take the posts with at least one play, then the highest, lowest and median play count, the ratio of highest to lowest, the ratio of highest to median, and the share of the creator's 10-post total that the single best post took. Tier and overall rows are the median (and quartiles) of those per-creator figures. One creator with only one viewed post is excluded, as in the source file. Handles are not carried into this file. user_profile returns rounded follower counts.",
