That's exactly what we did. Same value too. We just had a gentleman's agreement beforehand with all players.

We just came up with a number that worked for everyone. 100 million was beneficial enough to go for, but didn't take all night to do. You have 4 top players timing out every mode and doing this exploit during league it can take all night otherwise.

In Calm Before The Storm, you just need to trap balls on both flippers. Then shoot the right orbit with the left flipper and pass the ball on the right flipper to the left. When you trap the ball on the left, it holds up the upper left flipper too. You can shoot that upper orbit and the ball will roll off the held up upper left flipper so you can do it over and over and over. There are other ways to set it up, but that's how I do it when I have both balls trapped up. I did it once for almost an hour for fun after league and had my Beast Slayer jackpots up to 3 billion.
