Sushi Stock To Flow Rainbow

Hello everyone,
as always, I hope you are doing well.

To sum up:

The stock-to-flow is the number we get when we divide the total stock by the annual production (flow).
It indicates how many years are required, at the current production rate, to produce what is in the current stock.

The stock is simply the total in circulation, in our case, the number of Sushi in circulation.
On the other hand, the flow is the total number of Sushi created each year.

In our case:
- The number of new sushi issued is reduced every month
- The total number of sushi in circulation is set at 250 million
- The last reduction will take place in October 2023

The empirical formula of the stock to flow is, in our case: total number of sushi in circulation / number of sushi produced each month.
