[Spaceships] simply fuel math...

As this would have bearing on the fuel issue, has there ever been a question about the mass of a GURPS SPACESHIPS craft where it wasn't exactly what the tables say it is?

For instance, can you have a spaceship whose loaded mass is say 260 tons?

If there are 20 "units" to a ship, each 5% of its mass, and you want a 260 loaded ton mass, 260/300 = .867 units of the 20 normally used in a ship, or roughly 17 units used, 3 left empty.

Can one build such a ship using that design philosophy? If so, then determining its Delta-V value could be based on 260 tons instead of 300 tons?
