I was wondering how one could make attacks that deal a certain, set ammount of damage; say, not 3d, but always 11. I tried looking at Modifying Dice + Adds as a baseline, but I don't know how well that would work. P.S. And if there is a solution, how would I incorporate it into GCA, if possible?

Did you see the rules for Partial Dice (B62)? Each +1 damage is treated as .3 dice for purchasing purposes, so an attack which does exactly 11 damage would be the cost equivalent of 3.3 dice of whatever type. This represents a small premium over the normal cost, due to the slight advantage gained in knowing the exact damage potential of your attack.

Two dice equals seven points. So figure the cost of a 2d attack, and divide by 7 to get the cost per point.

Points x 0.3 = Equivalent dice of damage

So an attack that did exactly 20 points of damage would cost the same as a 6d attack.

This is already part of the Basic Set data file in GCA (on account of it's already part of the Basic Set). Add your innate attack, and check out the mods.

Rearranging that equation gives Points = 3.(3) dice, which is off. The expected value of a single die is 3.5, so a better conversion factor would be Points*(2/7) = dice. By this, 20 points would be about 5.7 dice, which rounds to 6, but for larger numbers, like 200 points, it would be 57.1, which rounds to 57, compared to 60 dice by your method.

The stats (average results) are: 1d = 3.5 2d = 7 3d = 10.5 4d = 14 5d = 17.5 6d = 21 7d = 24.5 8d = 28 ... Which gives number of dice x 3.5. But why making attacks that makes a fixed amount of damage? On living (and especially on moving) creatures, it is impossible to make two times exactly the same wound. A very feeble difference of angle of attack often results in a very different injury... That's why damage is rolled in GURPS. Furthermore, it adds unpredictability, which gives the feeling of something more living...

There is nothing "off" about this equation. I'm not making a suggestion here. I'm quoting the already established rules for this, which can be found in GURPS Characters under the Innate Attack advantage.

Apparently, the GURPS designers feel that being able to do a set amount of damage instead of a random amount is a slight advantage, and hence costs more. If you disagree with this, feel free to use a house rule instead, but this is the RAW.

The rule in question is for partial dice, not constant valued attacks. Even if it were, your equation is incomplete, since it fails to mention that 1 point is only 0.25 dice. I'd say that extrapolating a rule for partial dice in this way is most certainly a suggestion.

Personally, though, I'm suspicious of any mathematical guidelines provided by the developers, since these are the same people who thought that the rounding method used by almost everyone ever (excepting those whose highly precise work requires the round-to-even method) wasn't good enough for them...
