A leap into the chasing field

Youssef Nader finishes 21st at 51.11 after the wire recorded a jump from 25.28 earlier today. That observed score event carried the entry from 1,830th to 21st; those event ranks describe the move when it was recorded, rather than a complete comparison with yesterday’s close. The 25.83-point increase brings Nader much closer to the medal leaders, but still 5.97 points below tonight’s provisional gold score. Tufa Labs remains first at 88.06, followed by Yi-Chia Chen at 83.89 and rabbithole at 80.56, all unchanged since the previous close.

Improving is not always enough

The gold line rises from 55.00 at the previous close to 57.08. Kajetan Schweighofer adds 1.67 points to reach 56.11 but remains sixteenth, 0.97 short of the fifteen provisional gold places. masspeaks, fifteenth at yesterday’s close, is now seventeenth with its score unchanged at 55.00. ARCward Intelligence occupies fifteenth at 57.08. The boundary has become harder to clear even for an entry that improves.

Itsu’s climb survives the higher line

Muggle holds fourteenth at 59.17, up eighteen places and 17.09 points since the previous close. The entry’s listed account is nisshokuitsuki, directly linked to Itsu’s X account. In the original public post today, Itsu announced rank fourteen and joked about the electricity bill rising too. The close confirms that position, with Muggle 2.09 points above the gold score. This extends the Early edition’s story; it is the same gain, not a second improvement this afternoon.

Further advances down the field

Enes Kulak reaches twentieth at 52.78, up six places with a 7.92-point gain since the previous close. Nguyen improves by 4.58 points to 50.14 yet drops one place to 24th, another example of the field moving faster than an individual score. Hira Norm closes 63rd at 35.83 after the wire’s observed climb from 764th; the recorded score increase was 5.27 points. yukichi0403 gains 4.86 points to reach 46th at 38.75. The leaders are steady, but that stability masks significant movement farther down the board.
