Each store is performing better: the successful store lost its weakest sales person, the unsuccessful store gained a (comparatively) excellent sales person.

  What if that worst salesman in the good store was costing the store $50K, and making it $100K? Average is the wrong metric here. Something like profit is the right one.

    Sure, that's another metric.
