What factors will a court consider in determining whether a defendant was a leader or organizer of an illegal activity?

The commentary to Guidelines 3B1.1 indicates that in determining whether the defendant was a leader or organizer, the court should consider "the exercise of decision-making authority, the nature of the participation in the offense, recruitment of accomplices, right to a larger share of the profits, degree of participating in the planning, the nature and scope of the activity and the degree of control and authority exercised over others ..."
