So, 2.5 tons for a standard hull. I'm not sure why the compromise is needed, though.You could reach a compromise, in that it requires one full hull point to be counted as a spacecraft.
What purpose does a 2.5-ton minimum serve that is any different than a 5-ton minimum? Ot a 1-ton minimum? Or a fractional ton minimum? Any hit is going to FUBAR all of them. I say dump the artificial minimum and just let small hulls be super fragile, like they are.
