Against the front of the class, by track and class
| Track | Class | Sessions | Typical gap to class best | Closest |
|---|---|---|---|---|
| Hallett Motor Racing Circuit (1.80 mi) | STL | 4 | +0.615s (0.72%) | +0.580s (0.68%) |
| Circuit of the Americas (3.41 mi) | STL | 3 | +8.449s (5.48%) | +8.256s (5.35%) |
Gap is the driver's best lap in a session against the fastest lap in their class in that same session (zero is fastest in class), shown as time lost and as a share of the lap, so conditions cancel out and tracks can be compared. Typical is the median session.
