Quoted from king-pin:
One you reach super jackpot each hit collects the super jackpot and increases it by another 100 million.
Maybe I am misunderstanding your quote here, but that's not how the super jackpot scoring works. I'll list out my knowledge on how the scoring works.
Once you start your first multiball and score the tropical, fresh water, and deep sea jackpots, the super jackpot scoring round starts. The first round of super jackpots is valued at 100 million. The player can collect this jackpot as many times as they can, and each hit will be worth 100 million only. Example, if the player hits the captive ball once, the player scores 100 million. If they hit it again, the score is still only 100 million. If the multiball ends and they were able to hit the captive ball 5 times, they had scored 500 million worth of super jackpots.
When the player activates a second multiball and again scores the 3 regular jackpots, the super round starts out at 200 million. On the third multiball, the supers start at 300 million. On the fourth multiball the supers are 400 million, etc...
So it's not necessarily the amount of times you hit the captive ball, it's the amount of multiballs you've played while getting to the super jackpot round.
If you have time, you can watch Keith Elwin put on a clinic of scoring super jackpots, and how the scoring progression works.
