Not reliably. Rate correlates with brand, overhead and location as much as with instructional skill. A 420-dollar hour is roughly six times the national average, and there is no evidence of a six-fold difference in outcomes. What actually predicts results is whether the tutor diagnoses before teaching and whether the student does the work between sessions.
The two predictors named here are both observable before you pay. Ask how the first session diagnoses your specific errors, and ask what the between-session work looks like. A tutor who cannot answer either question concretely is charging for time rather than for outcomes.
