# int_constructor_structural_pace_qualifying

> One row per (race_year, race_id, constructor_id).

<Note>Part of the [Pace Baselines](/transform/families/pace-baselines) family.</Note>

One row per (race\_year, race\_id, constructor\_id). Car pace advantage in qualifying (one-lap trim) via same panel regression as race version. Different coefficient expected vs race due to fuel load and strategy differences. Single-lap setup may favor different cars.
