Expected values and probability calculations per lap of step-up banners in Final Fantasy Brave Exvius (FFBE)
- The very narrow focus of this project is odds on step-up summon banners where the only results we care about are on and off banner Rainbows (5* bases).
- All calculations are in full laps of the step-up banner, where 1 lap = completing a set of steps on the banner
- Calculations are also lapis-centric, meaning any extra goodies received from steps are ignored (e.g. 10%/30% tickets, UoC for limited units)
