Default I think I'm missing something.

Can someone explain to me how damage dice are calculated off average damage? I can understand that damage rating is equal to the number of times the average damage divides by 3.5, but what determines when I add +x and -y?

I'm not entirely sure what you're asking.

The 'average' of one die is 3.5.

So, if my damage is 5d+5, then my average damage is going to be (5*3.5)+5 - or 22.5.

If my damage is 3d-2, then my average is going to be (3*3.5)-2, or 8.5.

Hope that helps.

Not really, what determines that 8.5 to not be 2d6+1 or 2d+2 (average 7, average 8)?

Rounding would be according to the preference of the person doing the math.

Out of curiosity, why do you ask? I can't think of any published GURPS work which talks about average damage rather than dice.

Arithmetic.

The average of 2D6+1 is 3.5 x 2 +1 = 8, and of 2D6+2 = 9.

Brainfart, I've been awake for quite a while now.

Damage calculations. It also seems to come up with special ammunitions.

Yes, there are damage multipliers that don't work well with the d system.

Are you maybe looking for the Optional Rule: Modifying Dice + Adds box on B269? If you're adding large amounts, it allows you to convert a +4 to 1d, a +7 to 2d. Or are you trying to go the the other way? You might want to look at Partial Dice for Innate Attack, B62.
