Average Weapon damage calculatio - need another pair of eyes

[Ben2]

Hi guys

For a variety of reasons mostly involving things hitting me in the head I want to check the maths of something I'm doing with you guys.

I'm calculating average weapon damage for the different weapons in ACTA:SFU at various ranges.

I'm using the following formula

Weapon damage (at the range used) x Probability of hit

So a phaser-1 at 6" range becomes

2 x 0.83 = 1.66 points of damage

A phaser-2 at 6" becomes

2 x 0.66 = 1.33 points of damage

A photon torpedo (not overload) at 6" becomes

4 x 0.5 = 2 points of damage

A disruptor

2 x 0.66 = 1.33 points of damage

A plasma F (Average per d6 = 3.5)

7 x 1 (automatic hit) = 7 points of damage.

Am I doing this correctly or have I been hit in the head too many times?

I'm also creating a bang per buck value, using the formula

Non-alpha strike damage at 12" + alpha strike damage at 6" / points of ship

Is there a better way of expressing this in a non-whip out the graphical calculator way?

Its slightly wrong. Its accurate for damage hitting solely on the shields e.g. that plasma torp on a ship whose shields can take it.
However, it doesnt take into account penetration of shields by those weapons that can, or when the shields are stripped and subsequent damage from criticals nor the effects of Precise and Devastating weapon traits, nor does it handle lowering of damage from rolling 1s on the damage table.

For a 1st approximation its fine, for precise calculations its a bit off due to the above chained effects.

Yeah, I had assumed striking shields. Adding in hitting hull adds another bunch of match dependent on weapon effects and I'm not going into that level of depth.

For damaging

- standard weapons 1 in 6 bounce, 1 in 6 crit

- precise weapons 1 in 3 crit

However -

- devastating weapons 1 in 3 crit (1 in 6 chance to cause 2 crits) - is this an ok way of looking at it?

I'd like to see the finished averages. Very curious.

Plasma weapons should probably have an asterisk since it can be reduced by phaser defensive fire.
