The blue line in the lower panel represents the average power-law slope, computed over a two-week window. It is now crossing the long-term value of 5.9, which is the same exponent obtained from the full regression.

This indicates that the power-law trend itself is reverting to its mean. Even though the price has not yet converged back to the regression line, the directionality of the growth regime is being restored.

In other words, whenever price is temporarily pushed away from the power-law growth path, that deviation has historically been transient. The system consistently re-aligns with the underlying power-law trend over time.
