Growth label: **Growing** (about +41% a year, Dec 2021 to Dec 2022). Growth label: we compare total revenue on the oldest and the newest return shown above. Growing means revenue rose by more than 10% a year on average, Shrinking means it fell by more than 10% a year, and Steady means a change between -10% and +10% a year. The rate is the compounded yearly average between the two returns, so it hides ups and downs in between (see the table). We only label groups with returns at least a year apart and at least $5,000 of revenue on the oldest one. This is our own calculation, not an IRS rating or a judgment of quality.
