Right?

not exactly ... now fuel from external tanks loosing weight during the flight on tanks.

early external tank was 200kg( like in your example) and you fly some about few hours and that 200kg have no changes ... and when you drop tanks you lost from plane exactly 200kgof fuel ....

now fuel consumption from tank has an impact on weight total weight

I see. This is excellent. Long range flights will be more comfortable now.
