A typical post picks up 1.3K interactions against 459K followers, an engagement rate of 0.274%. Measured over 17 original posts, its engagement rate beats 84% of 3,917 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 44K times each, and 2.84% of those impressions turn into an interaction. That is about 9.65% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.2 post a day over the last 30 days, though only 37% of days saw any activity at all. Most posts go out around 11:00 UTC, and Friday is the busiest day of the week. Of the 17 posts sampled, 12% carry an image or video and 24% link out. The account's strongest tracked post pulled 4.6K interactions, about 3.7x its own typical post. Recurring topics include #にじさんじ, #はかせレポート, #加賀美ハヤト_1stライブbd.

Compared with accounts its own size

葉加瀬 冬雪⚗'s engagement rate beats 84% of the tracked X accounts closest to it in follower count (3,917 accounts, accounts of similar size (decile 7 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.

On engagement per impression rather than per follower it beats 80% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.

Engagement rate as a share of followers, across the 37,856 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 97,248 times apart and a linear axis would flatten everything below the median into a single point.
