Against the front of the class, by track and class
| Track | Class | Sessions | Typical gap to class best | Closest |
|---|---|---|---|---|
| Portland International Raceway (1.98 mi) | T4 | 4 | +5.391s (6.06%) | +5.218s (5.95%) |
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.
