How the price of Gacha and Re-roll tickets is determined

Both Gacha Tickets and Re-roll Tickets are issued on a Linear Schedule via Perpetual Gradual Dutch Auctions (also known as ). These operate just as would. However, unlike a traditional GDA, which have a limited lifetime, PGDAs are able to run in perpetuity. This is thanks to some creative research work by our team!
If you don't understand the complex terms above; what you need to know, is that the price in MUSU goes up when new Gacha Tickets are bought, and then decays downwards over time.
Notably, Kamigotchi World's PGDAs are Discretely Priced, meaning the math treats tickets as whole, countable items instead of as a smooth, continuous flow. This makes more sense in practice, since players always buy whole tickets, not fractions of them. To our knowledge, this is the first commercial implementation of said mechanism.
The GDA was selected for dissemination of the remaining Kamigotchi supply for several reasons. Most notably:
Dynamic pricing allows for price discovery in the open market.
Exponential price growth/decay, against a constrained MUSU emission rate, allows the mint to take place on a continuous, ongoing basis.
