READING THE CURVE
Trendlines minimize squared error in log performance across the full set of monthly observations, so the fits match the logarithmic chart. R² describes model fit; the higher score is shown above.
Concavity comes from a quadratic least-squares fit to the latest 24 monthly observations. A positive second-order coefficient is concave up; a negative one is concave down. It describes historical curvature, not a forecast.
Scale shows adjusted performance rebased to $100 on a logarithmic y-axis. Click the graph to inspect a month's date and indexed value.
