Just curious to know how you set ideal value of tracking formula constants?

Hi, Thanks for designing Inter Font. I have one question about Inter font. How did you figure out ideal values for a,b and c https://rsms.me/inter/dynmetrics/

1. I came up with good tracking values for a bunch of optical sizes (the "ideal values" in the sidebar)
2. Made a simple interactive graph tool (the graph above "ideal values" in the sidebar)
3. Trial and error until I found a fitting curve
