Measured over 33 original posts, its engagement rate beats 91% of 3,899 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.

That is about 22.4% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
