Weapon strength question

[Fatboy]

What is the stronger weapon, laser 1-4 or laser 1-6?

[Betelgeuse]

laser 1-6 is a stronger weapon
it has the chances of doing 1,2,3,4,5,6 damage (with the average being 3.5 damage)

compared to
laser 1-4
it has a chance of doing 1,2,3,4 damage (with the average being 2.5 damage)

and that doesn't take into account rounding errors that always favor the bigger hitters

[Bobby]

remember to take into account repeating and rate of fire as well, the 1-6 does do more damage, but ultimately it is damage done per time unit that really matters.(to a point, if the damage is too low it won't hurt resistant armors at all(rouning errors?))

[Betelgeuse]

yep that is what I was referring to when I said rounding errors Bobby

say you have a armor that takes 25% damage from lasers

then a 1-4 laser would do
0,1,1,1 damage (with an average of .75 damage)

and a 1-6 laser would do

0,1,1,1,1,2 damage (with an average of 1 damage)

edit: man working with flat percents is much easier than finding the averages of dice
