Holy cow. With 515,000,000 chips in play, conventional assessments would indicate a winner would be resolved when the BB is 515,000,000/20 = ~25,000,000. Extrapolating the
Structure Sheet, that puts the expected finish at Level 54. With a half-hour left in Level 38, restarting tonight, expect there to be a LOT of poker left before this gets wrapped up.
Expect heads-up to end with a major cooler and for Day 10 to be a marathon of attrition.
