Actually, World's Payout is higher than you stated. When I added up the advertised payouts, I came up with $73,240 in Guaranteed cash, 6 tables, a bunch of trophies, a couple of package deals for future tournaments, jacket for the master singles champ, plaque for the team event, plus 100% payback in 5 additional events. I'd say the advertised payout is pretty close.
Additionally, the top three finishers on open singles, the top 1 in Women's Singles and the top 1 in Junior singles each get about $1000 in travel expenses for the ITSF WOrld Championships in Nantes, France.
