Engagement
Early reading. We have captured 1 original post for this account, below the 8 we require before treating a median as settled. The numbers above describe what we have seen so far, not a finished profile of the account.
A typical post picks up 50 interactions against 925K followers, an engagement rate of 0.005%. Posts are seen about 48K times each, and 0.105% of those impressions turn into an interaction. That is about 5.15% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.03 posts a day over the last 30 days, though only 3% of days saw any activity at all. Most posts go out around 18:00 UTC, and Wednesday is the busiest day of the week. Of the 1 posts sampled, 100% link out. The account's strongest tracked post pulled 19K interactions, about 492x its own typical post. Only 1 original post have been captured so far, fewer than the 8 posts we want behind a median before treating it as settled. Read the figures above as an early measurement of this account, not as a finished profile of it.

Posting timing
This account posts most often around 18:00 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.

I’m excited to announce my memoir, Out of the Shadows, will be published by HarperCollins in North America on October 13, 2026. In the book, I break my silence to reveal everything I legally can about my investigations of UAP and non-human intelligent life on behalf of the U.S Government and the profound impact my work had on me and my family. We are at a turning point in human history and I am proud to play a role in opening the public’s eyes to the truth and bringing about long overdue disclosure.

Reading these numbers
A typical post picks up 50 interactions against 925K followers, an engagement rate of 0.005%. Posts are seen about 48K times each, and 0.105% of those impressions turn into an interaction. That is about 5.15% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.03 posts a day over the last 30 days, though only 3% of days saw any activity at all. Most posts go out around 18:00 UTC, and Wednesday is the busiest day of the week. Of the 1 posts sampled, 100% link out. The account's strongest tracked post pulled 19K interactions, about 492x its own typical post. Only 1 original post have been captured so far, fewer than the 8 posts we want behind a median before treating it as settled. Read the figures above as an early measurement of this account, not as a finished profile of it.
