What is missing here

  • Yi Zhou has a provisional hard rating (5–19 matches), so it is pulled part-way toward his overall rating rather than used at face value.
  • Yi Zhou's ATP ranking could not be confirmed against this week's list, so it is used with less confidence.
  • No recent-match record for Yi Zhou, so no rest or workload adjustment was applied on his side.
