Median within each tier, against the headline median (quarterly)
The blue line is the single number NAR-style reporting quotes. The gold lines are what each tier actually did. Log scale — the tiers span an order of magnitude, and on a log axis equal slopes mean equal percentage moves, which is the comparison being made.
