A new nearest challenger

Yi-Chia Chen is second on the evening ARC-AGI-2 public board at 82.64. The afternoon observation recorded a rise from 77.22 in third to 82.64 in second, moving her above rabbithole’s 80.56. Tufa Labs stays first at 88.06, leaving a 5.42-point gap. Chen’s prior-evening comparison is unavailable, so the recorded afternoon event is the measure of this move.

Tufa’s lead belongs to the team

Tufa’s leading score is unchanged against the previous evening boundary. Its ARC-2 roster lists Dries Smit, Jeroen Cottaar, Isaiah Pressman and Stefano Viel under their verified Kaggle handles. That is this competition’s four-account roster; it should not be confused with Tufa’s different ARC-3 entry. Behind the leading three, nvbanana remains fourth at 77.08, with cpmpml and darraghdog listed.

The chase below the podium

Domdolus Tolus is eighth at 65.14, up 13.47 points and three places against this edition’s comparison. The morning wire described a much larger rise from an earlier rolling window; tonight’s gain must be measured from the prior evening boundary. Dawid Kopiczko is seventh at 66.25 after a 3.19-point gain, ARC Raiders ninth at 64.58, and Majkel1337 tenth at 62.08 after adding 9.58.

Arcnights reaches the line, fshindo advances

Arcnights adds 16.81 points to 48.75, climbing from 216th at this edition’s baseline to 16th. The afternoon wire had observed the team at 15th; its unchanged score now illustrates how quickly a place can slip. Tonight’s gold-score threshold is also 48.75, compared with 47.92 yesterday evening. The score threshold alone does not settle a tied team’s medal position. fshindo climbs from 31st to 18th with an 8.33-point gain to 45.83, while shiiin9 rises from 273rd to 19th at the same displayed score. Public medal bands remain provisional.

A competitor’s satisfaction

In a public Japanese post on October 12, fshindo said reaching ARC-2’s medal range was especially pleasing after putting time and effort into the contest without results. Tonight’s fresh rise adds a new chapter to that dated reaction. The verified Kaggle account ffsscf links directly to @crysis44k; this ARC-2 entry remains distinct from the person’s ARC-3 team.
