This review reads relationship lag values from the Primavera P6 `TASKPRED` table. Raw `lag_hr_cnt` hours remain the source of truth; displayed days are converted at 8 hours per day.

DCMA 14-Point Schedule Assessment: Test 9 target is less than 5% of relationships with lag.
DCMA Test 10 target is zero relationships with negative lead.
