Let's do some more math!
I would say a "typical" result of PBM would be 0, 1, or 2 jackpots, and probably about even distribution as well. You'll likely have more unsuccessful visits the fewer jackpots you get, I would GUESS a typical number of visits for each of those scenarios is 3, 2, 3.
I think you get 5M to start? Frenzy points are probably in the neighborhood of 15M (that'd be 60 switches). So each PBM we're looking at base 20M.
The first visit to the powerfield lasts way longer than the rest, I'd say you could average about 10M the first visit, then 7.5M for the rest.
Now the jackpots: We know now they're 50M, but what if they were 10?
It each of the 3 scenarios, for 50M jacks you're looking at 0: 45M, 1: 87.5M, 2: 145M. For 10M jacks you're looking at 45M, 47.5M, 65M.
Averages for those are 50M jacks, 92.5M, 10M jacks, 52.5M.
You can fiddle with the numbers to model it better. The upside is way higher with 50M jacks obviously, but you might have a point leaving a potential 52M on the table.
