Chen keeps the advantage

Semwal changes the shape of the chase

Prabhav Semwal climbs from 293rd to 71st on the edition comparison, gaining 2.34 points to reach 34.25. That is a move into the top 100 from near its outer reaches, even as the leaders stand still. The overnight wire used a different rolling window and reported a starting rank of 289th; the edition’s midnight comparison supplies the 222-place net climb.

Pressure below the leaders

The team named by reaches 31st at 36.92, up 23 places and 1.70 points on the edition comparison. Koris Lab & Sho rises 61 places to 120th at 33.39. Earlier in the night, the wire reported Preferred ARC reaching 34th at 36.86 after a 3.69-point advance over its own window. These moves show why an unchanged top ten does not mean an idle field.

What the overnight wire does and does not establish

The wire’s Chen report compares against the previous day and records a 3.27-point increase to the current leading score. That gain was already in the midnight baseline. Its separate correction puts Yongjiehi Shi’s earlier climb at 454th to 87th; the starting position was inside the top 500. Neither item should be recast as a fresh move since midnight.
