A page of statistics about Colossus at
http://www.wsop.com/promotions/files...he-numbers.pdf
includes the stats:
Total # of Entries: 22,374
Total Prize Pool: $11,187,000
Total Places Paid: 2,241
1 st Place Prize: $638,880 (1,130 times the buy-in)
2241st Place: $1,096
Total # of Unique Entries: 14,284 (64% of entries) (New WSOP record)
(Bests 2006 WSOP Main Event - 8,773 – by a whopping 63%)
Total # of Players Re-Entering: 6,641 (46.5% of uniques)
# of Players Re-Entering Once: 4,885 (thus 1,756 players re-entered
more than once)
Adding up 14284 people entering the first time, plus 6641 players
entering a second time, plus 1756 people entering a third time gives a
total of 22681, not even including the entries from those who entered
a fourth time.
22681 - 22374 (stated) = 307 buyins missing.
Not sure if the above numbers include any refunds. But would that explain all the missing buyins?
