A Note About Structure
On Day 1a, the entrants played until 15% of the field remained. That turned out to be 28 minutes into Level 9. Day 1b then played the exact same amount of time, so today, the combined returning group began with 32 minutes left on the clock in Level 9. They will play two more levels after that for a total of 152 minutes before taking their first 20-minute break.
After that, the schedule returns to normal for a Day 2 - two more levels before a 60-minute dinner break, followed by six levels with 20-minute breaks every two.
Of the 512 who returned, 342 get paid, so the field will go to hand-for-hand sometime before dinner.
