Two names at the gold door

insuperabilehart rose from 28th to 21st on the day's score event, lifting its mark from 36.73 to 37.39. That leaves the team 0.59 below SparseTech, who hold the nineteenth and last provisional gold place at 37.98. Tong Hui Kang, whom the wire placed 20th at 37.92, still sits 0.06 short, and the gold line itself did not move all day. Two entries now press the same boundary, so a single further advance by either would change who holds a medal place. These public medal bands remain provisional.

A late leap into silver

jf liao produced the evening's largest observed jump. A score event shortly before the close lifted the entry from 1.07 to 32.70 and from 2,381st to 177th, which is above the provisional silver cutoff of 32.25. It is one result in a line of overnight and daytime climbers, but the size of the move stands out on a board of more than 4,500 teams. Robin also rose to 162nd at 32.81 from 31.99, a gain of 90 places over the edition baseline.
