Fleshing out LL's reply a little:

Basically yes... though see the comment about rounding errors, below.

...which means that the weapon now has a greater probability of having a

target to shoot at. The reason why the weapon size isn't exactly
proportional to the area is that it can only *actually* shoot at one
single
target per turn, even if there are multiple targets within its envelope.

Note that this mass-to-range formula DOES NOT WORK for the standard beam

weapons, because the current beam weapon masses themselves are already
rounded to the nearest integer value - specifically, in the case of the
B2
the mass fraction that was dropped was quite big. This means that if you

increase the range of a B2 by 50%, and increase its Mass by 100%, you're

introducing a rounding error of ~1 Mass relative to what the weapon
*should* cost - and the result is a weapon which is significantly better

(measured in bang-per-buck) than the standard B3.

Back to Tony's post:

Proposed and rejected. The B2 example above makes it obvious why: for
several of the published weapon systems the published mass ratings and
costs include rounding errors, and any simple multiplications of those
already-rounded costs will rapidly cause those rounding errors to grow
to
the point where they become balance problems.

This isn't very serious when only the damage is modified (since in this
case the main rival to the modified weapon is the original weapon -
their
range profiles are exactly the same), but it becomes very important
indeed
when the *range* (and thus the range profile) changes since in this case

the modified weapon doesn't compete with its unmodified version but with

weapons of other classes (eg., a B2 with 50% longer range competes with
unmodified B3s, not with unmodified B2s).

Because of this, the simple "multiply existing weapon by X" approach
only
works for *some* of the published weapons, but not for *all* of them. A
custom weapon design system needs to dig at least one step deeper, and

No, decreasing the range by *33*% allows you to halve the mass. (100% is

two-thirds of 150%, not three-quarters.)
