Thanks! All of our metrics are pretty well correlated with each other; you can see more information here.
Our primary metric is hours of engagement, which I didn’t use for this post because the data doesn’t stretch back as far. But the growth rate there is:
2020 (estimated): 90%
2022 (so far): 140%
Implied 3-year growth: 912%
More about how this is calculated and our historical data can be found here.
