Pager flicks are judged by when the finger moved, not when the move was handled; the counter counts the reachable posts again.

Right after a refresh, with clips warming, touch moves queue behind other work and arrive in bursts. The flick's speed was timed on handling, so a burst after a stall read as a fling (a short flick flew) and a stall before the last move as a crawl (a long flick took one step) (Adam, 2026-10-17: "sometimes a quick long flick only proceeds to the next video and doesn't coast as i would expect it to and sometimes the opposite happens -- a short flick does fly"). Each move is now timed by its event's timeStamp, when the finger made it; moves that share one (synthetic ones can) fall back to the handling time.

The counter goes back to counting the posts in the carousel (e529ab1 undone): counting the ones still warming confused, since they can't be scrolled to (Adam: "maybe we should go back to showing the total loaded").

tools/pager-swipe-fly-test.js: a gentle swipe whose moves are handled in one burst goes one post; a fast flick whose last move is handled 300 ms late still flies (it took one step with the old timing). pager-ready-gate is back to "the counter grew". pager-ready-gate, pager-tap-slop, pager-seek-hide, pager-first-frame, thread-pager and profile-pager pass.
