# int_lap_residual_decomposed_qualifying

> One row per qualifying lap.

<Note>Part of the [Residual](/transform/families/residual) family.</Note>

One row per qualifying lap. 7-term decomposition mirroring int\_lap\_residual\_decomposed but with qualifying-specific coefficients (near-zero fuel, cliff-suppressed compound degradation, quali-mode car pace). Grain: lap\_id. Enables quali-vs-race skill comparison.
