Yes, the second scenario is the more common, and naturally I've encountered it in NG as well.
I've been both guilty of, and witness to, hitting the T1T early in the past, and for most it serves as a lesson to not be so hasty. The concern there, being those who don't learn from the event. But that's another story.
When you have one engine which is slightly slow to accelerate with the autothrottle engaged, but both appear to accelerate normally without the autothrottle- what function does the autothrottle play that might cause this? Do both engines accelerate independently to the target N1 based purely on physical action of the autothrottle or some rough control/matching?
