A typical post picks up 2.9K interactions against 722K followers, an engagement rate of 0.395%. Measured over 40 original posts, its engagement rate beats 90% of 3,882 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 91K times each, and 3.12% of those impressions turn into an interaction. That is about 12.7% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.4 posts a day over the last 30 days, with activity on roughly 60% of days. Most posts go out around 23:00 UTC, and Sunday is the busiest day of the week. Of the 40 posts sampled, 53% carry an image or video and 18% link out. The account's strongest tracked post pulled 53K interactions, about 19x its own typical post. Recurring topics include #オーイシマサヨシ, #オーイシ武道館, #大石武道館.

Compared with accounts its own size

大石昌良【オーイシマサヨシ】's engagement rate beats 90% of the tracked X accounts closest to it in follower count (3,882 accounts, accounts of similar size (decile 8 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 82% 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 37,701 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 104,204 times apart and a linear axis would flatten everything below the median into a single point.
