B777 difference between APU to Packs and Packs off T/O
All...

Can someone explain this difference to me.

It seems that in either instance, the bleed air will not be used from the engine to the packs and therefore would be the identical same performance adjustment... but obviously I'm missing something as there are the two separate checklists in the supplementals.

Thanks
