What is the significance of a Ground idle figure being out of limits if everything at Flight Idle is normal? Ground idles within limits would mean both engines driving equally I accept.

I'm not 100% sure, but my thinking is, if it's too high then lift can be produced. I may be wrong. When I worked on them, the FCU's were a real b*gger to adjust. Experience told me to account for spring historious. Wind it out a bit further than the book says and then back in again.
Modern electronic FCU's are so much better.
