Measured over 11 original posts from a 30-day window, last computed on October 16, 2026.
Engagement
A typical post picks up 286 interactions against 310K followers, an engagement rate of 0.092%. Measured over 11 original posts, its engagement rate beats 58% of 20,444 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 25K times each, and 1.16% of those impressions turn into an interaction. That is about 7.98% 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, though only 40% of days saw any activity at all. Most posts go out around 01:00 UTC, and Thursday is the busiest day of the week. Of the 11 posts sampled, 64% carry an image or video and 36% link out. The account's strongest tracked post pulled 23K interactions, about 81x its own typical post.

Compared with accounts its own size
Peter St Onge, Ph.D.'s engagement rate beats 58% of the tracked X accounts closest to it in follower count (20,444 accounts, accounts of similar size (decile 9 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 47% 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.

Posting timing
This account posts most often around 01:00 UTC, and Thursday 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 | 64% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 36% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 64% 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.
- 36% 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 301 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.

π¨ JUST IN: President Trump says US GDP growth could be up to +20% PERCENT if the Fed just got out of the way "We could have a GDP of 14, 15, 16 and 20. But every time you do well, we just announced great numbers and so now they're talking about raising interest rates, it's RIDICULOUS because success and growth does not cause inflation!" "If we announced good numbers, interest rates went DOWN . Now if you announce good numbers, interest rates go UP because they're so afraid of inflation!" "But what they're doing is they're really saying you can never do, you can never really step on the gas."

An update to my list of the TFRs decomposed into the Total Maternal Rate and the number of Children per Mother (Family size). Some countries have similar TFRs, but they differ a lot in how they attain them (Do they have low childlessness and small families or the other way round?).

Reading these numbers
A typical post picks up 286 interactions against 310K followers, an engagement rate of 0.092%. Measured over 11 original posts, its engagement rate beats 58% of 20,444 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 25K times each, and 1.16% of those impressions turn into an interaction. That is about 7.98% of the follower count, which is the gap between an audience on paper and an audience in a timeline.

- What is Peter St Onge, Ph.D.'s engagement rate on X?
- Peter St Onge, Ph.D. (@profstonge) has an engagement rate of 0.092%, based on the median interactions across 11 original posts from the last 30 days against 309,889 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.092%, Peter St Onge, Ph.D. sits above the 25th percentile of the 205,475 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @profstonge have real engagement?
- Its engagement rate beats 58% of the tracked X accounts closest to it in follower count (20,444 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @profstonge post?
- Most posts go out around 01:00 UTC, and Thursday is its busiest day, at roughly 2.37 posts per day across the measured window.
