Note that Lakisha went 5th in the Final Eleven, which has historically been bad luck at F9.

ETA: Cgnu's note at F9 notes that the F11 5th performer has been jinxed at F9. In Season 2, Corey Clark was eliminated through disqualification, then, for the next two seasons, the eliminee at F9 was the 5th performer at F11. Last season, McPhee broke the curse, actually, although that's probably little comfort to Camile Velasco and Nikko Smith.
