That number is thanks to Azircon! He always pushes me to calculate new metrics, sending me down a rabbithole of information and interpretation. I was surprised, too, that I can calculate that, but am happy that I now know how to.
And yes, the community part is important to me. I want to see if I can establish HBD or a Cotacachi-Coin as a local currency. For one, that helps to combat the extraction by credit cards. And it helps to keep the money within the economy. In the first article, linked in the post as well, I calculated that the economic impact of the Farmer's Market over a year is almost 1M USD, going through 4 levels of local impact (80% retention on level 2, 40% on level 3, 20% on level 4). Keeping it local is the best solution for everyone. Except the big bad companies, but that's another bonus in my eyes.
