[Spaceships] simply fuel math...

Just out of idle curiosity...

Would the formula for Realistic Delta-V from TRANSHUMAN SPACE apply here?

Presumably, each of the elements has a given weight (5% of the total mass) and consequently, the fuel mass would be equal to 5% per tank, and if using smaller SM tanks, each SM-1 tank relative to the overall SM of the ship, would add 1/3 of 5% or 1.67% per tank at the smaller size.

The only thing missing is the ISP for the fuel, but - I suspect that can be reverse engineered from the Delta-V values given with the original rules.

Just thinking aloud (so to speak).
