I like 15% paid too but it does not seem very realistic to get in the money in one day with your structures. It's a great problem to have: the structures are really good!
Let's take the first event, the Ultimate Goliath. The tournament starts a 11am, and with 16 levels and a dinner break, play will stop around 11.30pm! It's more than enough, adding more levels is not a great option IMO.
My guess is, even with 15% paid, you won't reach the bubble before level 18 or 19.
That would be a really loooooong day, not a great experience IMO.
Could work only for events with 30-minute levels or with the Goliath Milly where players get "only" 20k chips to start with.
