You must have missed the word "basically." Using the percentages above and assuming 50,000 entrants, you get:
7,000 from lottery (US and international)
22,000 from guaranteed entry
15,000 from Int'l Travel Partners
6,000 from Charity
Assuming the lottery is split 50/50 (my hunch it isn't and non tri-state area domestic people make up the bulk), then there are 3,500 international lottery people. 15,000 tour package people greatly dwarfs the 3,500 lottery internationals. Is that surprising considering that the tour package numbers are more valuable?
