If I read it right Johnson was getting a 20% loss rebate any day his loss amounted to $500,000 or more. If you bet $100,000 a hand and lose five hands in a row you get $100,000 back. Then you play another five hands for $100,000 and win them all. You broke even on the hands won and lost. You went 5 for 10. But you would be ahead $100,000.
