Measured over 13 original posts, its engagement rate beats 76% of 3,848 tracked accounts of a similar size. Comparing inside a size band matters here: engagement rate falls as accounts grow, so a raw rate would mostly just re-measure the follower count. Posts are seen about 154K times each, and 0.495% of those impressions turn into an interaction. That is about 28.2% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
