A typical post picks up 1.5K interactions against 526K followers, an engagement rate of 0.285%. Measured over 46 original posts, its engagement rate beats 84% of 3,758 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 21K times each, and 7.04% of those impressions turn into an interaction. That is about 4.05% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.9 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 21:00 UTC, and Wednesday is the busiest day of the week. Of the 46 posts sampled, 72% carry an image or video, 7% are part of a thread and 7% link out. The account's strongest tracked post pulled 168K interactions, about 112x its own typical post. Recurring topics include #oh07, #va01.

Compared with accounts its own size

Captain Mark Kelly's engagement rate beats 84% of the tracked X accounts closest to it in follower count (3,758 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 96% 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.

Where this sits in the catalog

At 0.285%, Captain Mark Kelly sits above the 50th percentile of the 36,378 accounts in this comparison. That places it in the above the median band, which runs 0.08% to 0.432%.

Engagement rate as a share of followers, across the 36,378 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 107,364 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 21:00 UTC, and Wednesday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

    The White House decided there was a threat so great that Donald Trump was secretly moved to another plane but they never told the passengers on Air Force One. Cowards look out for themselves. Leaders look out for their people. https://t.co/BcIYJEkrXb

    Donald Trump and Pete Hegseth have completely botched this war. Yesterday, Trump said that Phase 1 is to open the Strait of Hormuz. His goal is now to fix the thing he broke. And the only thing the American people have to show for it is higher prices. https://t.co/WJtMJlTbVO

    I spoke to a grandmother today worried about her 21-year-old grandson who's aboard the USS Abraham Lincoln. He’s lost 20-25 pounds and is struggling with depression. And so-called leaders like Pete Hegseth aren’t doing a thing about it. https://t.co/sueDJajmPV

    North and South Korea are still technically at war. Our ability to help defend our ally against the North Koreans is because our forces are well trained and able to coordinate with the South Koreans. Hollowing out these joint exercises is shortsighted and a mistake. https://t.co/VLO3t7Ghbf

    Eight years ago today, we lost John McCain. He served our country with courage throughout his life — as a Navy pilot who was taken as a POW, a Senator for over 30 years, and a leader who never stopped fighting for Arizona. That kind of service is worth honoring, today and always.

    ICE has been detaining spouses and parents of servicemembers. These are mothers, fathers, husbands, wives — people who keep families together while their loved ones serve. I'm fighting this and working to get them back to their families because they deserve better than this. https://t.co/yUDYo0Z8d3
