Engagement
Early reading. We have captured 7 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 1.6K interactions against 183K followers, an engagement rate of 0.863%. Posts are seen about 46K times each, and 3.45% of those impressions turn into an interaction. That is about 25.1% 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 23% of days saw any activity at all. Most posts go out around 07:00 UTC, and Saturday is the busiest day of the week. Of the 7 posts sampled, 100% carry an image or video and 14% link out. The account's strongest tracked post pulled 31K interactions, about 20x its own typical post. Recurring topics include #gt7, #granturismo, #gtws. Only 7 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 07:00 UTC, and Saturday 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 | 14% 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.
- 14% 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 354 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.

初期のグランツーリスモ・シリーズは、必ずゲームディスクと、同梱ブックレットとをセットにして販売していました。 「体験するグランツーリスモ」と「読むグランツーリスモ」の組み合わせです。 グランツーリスモを通じて、自動車とは何か、自動車の物理とは何か、ドライビングとは何か、に興味を持ったプレーヤーや、それが昂じていま自動車業界で働く方もたくさんいらっしゃると思います。 近年になって、コスト的に見合わないという理由で、物理的なブックレットの同梱はなくなっていたのですが、とはいえ自動車とは何か、は、やはり伝えていきたい。 そんな動機から、過去の同梱ブックレットの内容を再構成してWebで公開しました。最新の知見や業界動向もふまえた新しい改訂版を作りたいと思っていますが、ひとまずこれまでの集大成です。 「The Gran Turismo Magazine Beyond the Apex」 「読むグランツーリスモ」です。 https://t.co/8J5nuMfWxM In the early days of the Gran Turismo series, the game disc was always sold as a set with an accompanying booklet. It was a combination of “experiencing Gran Turismo” and “reading about Gran Turismo.” I believe there are many players who, through Gran Turismo, developed an interest in what cars are, the physics of cars, and what driving is all about—and many of them have gone on to work in the automotive industry as a result. In recent years, the inclusion of physical booklets was discontinued because it was deemed uneconomical, but we still want to convey the essence of what a car is. Motivated by this, we’ve reorganized the content of past bundled booklets and published it online. While we hope to create a new, revised edition that incorporates the latest insights and industry trends, this is, for now, a compilation of everything we’ve covered so far. “The Gran Turismo Magazine Beyond the Apex” “Gran Turismo to Read.”
