I don't think anyone gets paid a lot more than $51 but it's possible I read it wrong.
It read like more people get $51 but no one gets more than $51.
It wasn't 100% clear to me if some people could maybe get up to $51 twice (ie. automatic claim followed by manual claim) but it read fairly explicitly to me that they couldn't get it more than that.
The bit at the end where they pay out all the extra money doesn't read like it goes to the same people multiple times but instead opens up to an ever expanding pool of people (there are hundreds of millions of prime members).
Dont pay people automatically so that the remaining ones who do claim it get paid a lot more than 51$.
In fact, a lottery where only 1% of victims got 5000$ would be even better.
America loves its inequality. Stop making us equally poor and let the lucky few of us get a 1 oz bar of gold!
