Engagement
Early reading. We have captured 3 original posts 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 94 interactions against 67K followers, an engagement rate of 0.141%. Posts are seen about 1.7K times each, and 5.53% of those impressions turn into an interaction. That is about 2.55% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.43 posts a day over the last 30 days, though only 30% of days saw any activity at all. Most posts go out around 12:00 UTC, and Friday is the busiest day of the week. Of the 3 posts sampled, 100% carry an image or video and 33% link out. The account's strongest tracked post pulled 6.5K interactions, about 69x its own typical post. Recurring topics include #goodshabbos, #shabbatshalom, #theendurancecode. Only 3 original posts 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 12:00 UTC, and Friday 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.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 100% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 33% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 100% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 33% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts.
- Its average post runs 327 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

Shabbat Shalom! We now stand in the midst of the Ten Days of Repentance, preparing for Yom Kippur—a time to pause, reflect, and strengthen our connection to Hashem. May this Shabbat bring us peace, inspiration, and a meaningful preparation for Yom Kippur. Good Shabbos! https://t.co/bRF6LqEuPk

Your push-up count may reveal more about your heart health than you think. In a 10-year study of 1,104 active male firefighters aged 21–66, men who could complete more than 40 push-ups had a 96% lower observed rate of serious heart-related problems than those who could complete fewer than 10. These included heart disease, heart failure and sudden cardiac death. Push-up ability was a marker of health, not proof that push-ups prevented these problems. Still, it is a powerful reason to start building your strength today. Start where you are: wall, counter, knees or floor—one strong repetition at a time. --- #exercise #longevity

- #GoodMorning All! Are you enjoying a nice cup of coffee right now? I hope so! A Massive Recent Study Found: For those sitting over six hours daily, the 58% higher mortality risk vanishes if you drink coffee! Coffee consumers slash cardiovascular death risk by 54% and all-cause mortality by over 30%!! This 13-year study of 10,639 participants suggests your daily brew effectively neutralizes the lethal hazards of a sedentary desk job. While the study focuses on multi-year outcomes rather than specific quantities, similar large research studies suggest that drinking two to three cups daily secures these protective benefits. But as a Sleep Science Coach, I must say it’s important to still try to have coffee typically in the mornings before 11 am or 12 noon (for some even earlier depending on sensitivity to caffeine), as a sleep hygiene best practice. - Wishing you a day of high energy, clear focus, and deep positive wellbeing! Cheers! ____
