777 Fuel Index Question

To any 777 trainers / people that understand it...

Why do you enter the MACTOW into the CRZ CG above 98 tonnes of fuel, rather than MACZFW. I understand its something to do with the fuel index but its unclear.

Also does it effect the optimum altitude in the FMC?

Thanks in advance!
