It's been over ten years since I worked it out and I've hardly thought about it since, and of course I have no way of knowing whether this is the 'proper' way of calculating it, but here goes:

Start with the firing chart. Add up all the to-hit numbers in the chart. e.g. Firing Chart G would be 7+7+6+6+5+5+4+3+2+1 = 46

Multiply by the damage for torps/the maximum power for beams.

Now divide by 168.

For beams add on

0.03 for each hex of range that adds 1 to the damage.

0.07 for each hex of range that adds 2 to the damage.

0.14 for each hex of range that adds 3 to the damage.

Round to the nearest 0.1 (most of the weapons in the construction manual are rounded up but some are rounded down...)

If the ship is cloaked multiply by 1.5

Example 1, FH-13, firing chart T, add up all the to-hit numbers and you get 107. Max power is 8. Does +1 at 1-5, +2 at 6-12 and +3 at 13-18.

So that's ((107 * 8) / 168) + (5 * 0.03) + (7 * 0.07) + (6 * 0.14) = 6.575 rounded up to 6.6 as given in the construction manual.

Example 2, KP-4, firing chart Q, add up all the to-hit numbers and you get 92. Damage is 18.

(92 * 18) / 168 = 9.857 rounded up to 9.9, (construction manual rounds down to 9.8)

Allowing for rounding errors, as in example 2 above, the Fed and Klingon weapons match this formula. About half the Romulan weapons match it (I don't know how they calculated plasma bolt WDFs and so don't count them), all but one of the Orion beams match it, the Gorn beams match, but the Gorn torps don't. Generally the discrepancies are small.

Maybe someone else has a better formula.
