mmm! - quite correct.
But taxi fuel can be higher to give a higher than specified MTOW. and LDW, strictly Freight Dog calculation in Africa.
EZFW weight can be used for planning purposes until the AZFW is known.

Your question
another question about the ZFW / ZFM debate, why plot it on the trim chart?
It is a reference for the PIC to enter into the FMC and for the calculation of the Vr speeds. The loadsheet is a legal document and has to be anotated and signed correct by the loadmaster/dispatcher and the Captain.
Hope this helps
