Extremely interesting result out of NAIC Seniors (452 players):
After round 10, my sim projects an 8-1-2 cut *99%* of the time, but it actually had an 8-2-1 cut. My sim assumes players at X-1-1 will ID into cut if there is a high chance of X-1-2 cut, but that didn't occur. (1/2)
I extended this work using the same assumptions for 65-512 player tournaments, which covers smaller events as well as Juniors (born after 2013) and Seniors (born 2010-2013).
While the pattern is the same, the shift to the right means these are much less likely to see X-1-2 cuts.
