Loadsheet Discrepencies

[GMane]

Hello, I notice there are consistently differences between the ACARS loadsheet and the OIS loadsheet page, specially involving the ZFWCG. See the pictures, unless I misunderstood the MACZFW is not the same as ZFWCG??

Also it would be good to have a live ZFW on the 'Loadsheet' page of OIS or a send to FMC option like the TO speeds

Thanks
