When Lachen reposts someone else — how soon after the original? The lag between the source's post and the repost shows how close he stays to the front's pulse. Almost half of forwards land within the first 15 minutes.
Posts from officials and the military (Fedorov, Kim, Azov's 1st Corps) land in the channel within 1 min median — an order of magnitude faster than meme or entertainment sources in the same top list (5 min). Not feed-reading — monitoring priority frequencies.
