  1. aRelative good performance is defined as being in the top 25% of the total QoC score distribution
  2. b2Absolute good performance is defined as performing ≥80% of all observed routine L&D actions correctly; 2.84% of deliveries observed demonstrated absolute good performance
  3. cMean = 7.48, median = 7
