This sheet contains calculations for the average wounds per turn for a variety of units and weapons, firing against a variety of test-dummies. The stats for the attacker are on the left, while the average wounds are on the right, with the test-dummy chart further to the right in each case. Below the primary chart, you will find a second chart, which displays average points per wound per turn for each matchup. Model cost and weapon/wargear cost are now in different columns, considering the sum of both (plus any relevant additional wargear) in the cost efficiency charts.

This is by no means an exhaustive list, but instead is using choice bits from each faction I work on. Provided on this page is the full formula I use, such that you can do your own calculations for anything I haven't covered already. Do note that more efficient does not always mean better, as the points-efficiency chart does not take into account factors such as range, durability of the unit or mobility. Context will always be important, units do not exist in a vacuum. These charts are simply intended to give you ballparks for what you can expect when you use a particular unit to attack at a particular target, and approximately how expensive that firepower is relative to alternatives. Happy math-hammering!

Shots per Model
The number of attacks each model gets when they attack with this weapon
20
Die/Fixed
Indicates to the formula whether the D value represents a flat damage or the size of a damage-die
21
D
Damage (Die or fixed value, depending on preceding)
22
Unit Size
Number of models in the unit, generally minimum unit size with this weapon, or the minimum to get a buff based on number
23
Weapon costCost of weapon
24
Unit cost
Cost of unit (per model)

Prob. of normal damage on successful cast (27/36) times average of d3 (2) plus prob. of enhanced damage (3/36) times average of d6 (3.5) = 1.79

Reroll To-Wound
To-wound factor changes to 1-(1-[Normal to-wound factor])^2

Reroll To-Hit
To-hit factor changes to 1-(1-[Normal to-hit factor])^2
