Actually, you did win your entry fee back minus the $10 ace pool money that was deducted from every entry.
The PDGA does not mandate that last place money get their entry fee back anymore now that the scale is flatter and we pay out many more spots than used to be required. It is only due to the deeper payout in recent years that you won any money at all as Pro worlds used to pay only the top 1/3. Sorry if you somehow feel cheated but we exceeded all requirements. We just ran the second richest Pro worlds in history and all I hear is complaining. Now I know why nobody wants to run pro worlds.
