Exceeding leadership

[monkeydog]

Could someone clarify what happens when this occurs? I thought I read some where that if you exceed a stack's leadership up to but less than 150%, then you lose control of th unit and it may attack the enemy or it may not. When the leadership is 150% or more, then the stack becomes frenzied and will attack the enemy as well as your troops. Is this correct? I thought the other night one of my stacks slightly exceeded its leadership and it attacked my own troops.
