Problem is just checking the points per wounds or the average wounds can hide more efficient results hidden in statistics.
That discovery in rolling Mathhammer values was why I put my math hat and explore more deeper the Stathammer level.
Example: (exagerated values, but it's for the sake of explanation)
You shoot at a 5-men unit.
"A" has 4 average wounds , 5 shots, with 99% to deal >= 3 wounds, 50% to deal >= 4, 1% to deal >= 5
"B" has 3.5 average wounds , 20 shots, with 70% to deal >=2 wounds, 60% to deal >=3, 40% to deal >=4 (close to 50% of "A"), 30% to deal >=5
Which one you may want to choose:
"A" that can wipe out the opponent 1% of time but deals more average wounds ?
"B" that can wipe out 30% of time with lesser average wounds and more chance to not kill entirely the target ?
"A" is sure to shoot twice to wipe out the target, but will maybe never kill it in one turn.
"B" already know that it will need most of time to shoot twice, but has more chance to wipe out in one turn.
Your choice is then based on what you have in your army that can handle the single remaining wound when "A" fires. Or if you don't care to shoot "A" twice.
Or If you want units that evolve less supported by other units and can afford two rounds of firing.
My tool provides the chance of wiping out or taking morale check to help with that.
- Of course, when average wounds are equal, the unit that to shoot more has a clearer advantage, but when average is not equal, things get blurred
- I use an example of average wounds, but it is a same explanation for points per wounds.
Stathammer is not a magical "Win" button, just a way to choose better which unit fits a particular situation.

That's truely true. I wouldn't find a better way to tell it.
