It's not a pointless question really with many loadsheets now being simplified due to computer based W&B.
It depends on what the allowable LMC limit is before a new W&B is required. In our case (A319) changes up to 500kg, with certain other restrictions in individual holds, may signed off without recalculating Balance. Just a quick weight adjustment calc and go. Outside those limits it's a full W&B.
The actual design of the loadsheet means nothing other than how much space their is to record the LMC.
