For other managers experience we know it, too training speed will be reduced if you win a star "in virtual form" without assign the skill points.
Is true that too we can say that in this game there's no a place of rules that say how work that, and will be interesting to create it... so for now.. we have the experiences of managers that during these years in the forum proved how the game works, and I can assure you that unassigned cones count in the general Quality, but not in visible mode.
