In the example given the player pays $6.32 to save their $100 investment when they have a 6.53% chance to lose.

Is this a typo? The real cost as I understand it should be $6.53? Is there some small concession the player gets or am I misunderstanding this?

Maybe I have been missing out on a ((6.53-6.32)*100/6.32) 3.3% freeroll on money spent on insurance...
