I wrote a script once to figure out the non-jackpot prizes - I don’t remember where it is and I’m too lazy to rewrite it, but it was a nice piece of change.
For instance, the $1,000,000 for five numbers gives you $25 million, since you would have the 5 numbers 26 times (once for the jackpot, and the other 25 power ball choices).
I do recall reading somewhere that the $1 million is actually limited by it’s weekly pari-mutual value, so if a lot of people hit it, you might not get the full $1 million for it.
