Between 1 April 2016 and 30 April 2017— estimated from Telegram’s id allocation, not measured. How this range is calculated.
2 measurements taken within a single day. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 904–906 and does not start at zero.

ERR is average views per post over the last 30 days divided by subscribers, the definition TGStat uses, so this figure is comparable with the one you will see elsewhere. It falls structurally as a channel grows: a high ERR on a small channel and a low one on a large channel describe reach mathematics, not quality. We publish the figure and the sample it came from and pass no verdict on it.
ER is defined industry-wide as (forwards + reactions + comments) ÷ views— note the denominator is views, not subscribers. Telegram’s public web preview carries views and reactions but not forward or comment counts, so the reaction rate above is the reactions term only and is therefore a floor: the true ER for this channel is higher by an amount we have not measured and will not estimate. It is computed over the 7 of 8 measured posts that carry a reaction reading, and over those same posts' views.

Readings taken

Views are a single reading per post, taken at the time above. A post published in the last day or two is still accumulating views, which pulls the 30-day average down slightly. That is a property of the standard definition rather than a fault in it, so we keep the definition rather than “correcting” the number into something nobody can reproduce.
Precision. Telegram publishes view counts on its public widget in short form — 8.12K, 3.7M — so any reading at or above 1,000 reaches us rounded to three significant figures, and only counts below 1,000 are exact. Averages and rates derived from them are shown to the same precision rather than to the unit: a figure like 3,701,250 would assert digits nobody measured.
Reaction counts are published per emoji and rounded the same way, so a total below 1,000 is exact and a larger one is a sum that may carry a rounded component from each emoji above 1,000. Because it is a sum, it does not look rounded — read a large reaction total as three significant figures per contributing emoji rather than as the figure it prints.

Lifetime counters from Telegram’s own channel header, read 6 August 2026 — not the date at the top of this page, which is when the subscriber count was last read. A count marked ≈ was rounded by Telegram before we ever saw it — t.me prints these counters in full below 1,000 and to three significant figures above, so ≈142,000 means somewhere between 141,500 and 142,499.
Reaction mix
126 reactions across 19 posts, in 6 distinct kinds. The most used accounts for 51.6% of them.

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 19 of the 20 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 126reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 20 most recent posts we hold, published 22 December 2025 to 2 August 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.
05-Qualification of Datum Features
این متن آموزشی بر روشهای استانداردسازی و تایید ویژگیهای مبنا در نقشهکشی صنعتی تمرکز دارد تا تفاوت بین سطوح فیزیکی قطعه و سطوح مبنای ایدهآل را مدیریت کند. نویسنده توضیح میدهد که چگونه از تلرانس تختی برای کنترل ناهمواریهای سطح اول استفاده میشود تا پایداری قطعه حفظ گردد. در مراحل بعدی، تلرانس عمودبودن به کار گرفته میشود تا رابطه دقیق بین سطوح دوم و سوم را نسبت به مبناهای قبلی …
04-Tolerancing Unopposed Surfaces (use profile tolerance instead)
۲ اوت ۲۰۲۶
این ویدئو توضیح میدهد که سطوح غیرمتناظر یا غیرروبهرو را نباید به عنوان ویژگیهای سایز در نظر گرفت، زیرا اندازهگیری آنها با ابزارهایی مانند میکرومتر غیرممکن است. نویسنده تأکید میکند که استفاده از تلورانسهای عددی ساده برای این قطعات باعث سردرگمی در بازرسی میشود، چرا که نقطه صفر یا مبنای اندازهگیری در آنها مشخص نیست. برای حل این مشکل،…
03-Limits of Size (Rule #1)
این ویدیو به تشریح قانون شماره ۱ در استانداردهای مهندسی میپردازد که محدودیتهای ابعادی قطعات صنعتی را تعیین میکند. طبق این قاعده، یک قطعه باید همواره دارای دو ویژگی اصلی باشد: اندازه محلی که توسط ابزارهایی مانند کولیس اندازهگیری میشود و پوشش جفتشونده که حداکثر فضای اشغالی قطعه را مشخص میکند. برای اطمینان از دقت تولید، قطعه نباید از آستانه مجاز فراتر رود و باید بتواند در یک گیج کنترل…
02-Sample Part with Geometric Tolerancing Indexer Plate
۲ اوت ۲۰۲۶
این متن به آموزش تلرانسگذاری هندسی (GD&T) از طریق بررسی یک قطعه صنعتی به نام صفحه شاخص میپردازد. نویسندگان توضیح میدهند که چگونه ویژگیهای فیزیکی قطعه، مانند سطح مبنا (Datum) و تخت بودن، نحوه اتصال و عملکرد دقیق آن را در یک مجموعه مکانیکی تعیین میکنند. در این منبع تأکید شده است که تلرانسگذاری ابزاری برای انطباق هندسه کامل ریاضی بر قطعات واقعی و …
01-Tolerances in Perspective
این ویدیو آموزشی به بررسی نمادهای استاندارد و ابعاد میکروسکوپی در نقشهکشی صنعتی میپردازد. مدرس توضیح میدهد که نماد ویژگی مبنا (Datum) برای هماهنگی جهانی با استانداردهای ISO دستخوش تغییرات بصری شده است تا درک نقشهها در سطح بینالمللی یکسان باشد. بخش مهمی از محتوا به تجسم اندازه رواداریها (Tolerances) اختصاص دارد، جایی که مدرس از تار سبیل گربه به عنوان معیاری برای درک ضخامتهای بسیار …

Showing the 12 most recent of 20 posts we hold for @Gadoot. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
Forward network
Republishes
Channels on the register whose posts this channel has forwarded.
Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.
Mentions
Names
Channels on the register whose handles appear in this channel's posts.
A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
