Too bad you didn't calc on the
ACTUAL damage you do, which is average damage. (because you never shoot maximum damage all the time)
the formula for average dmg/s is like this:
(attacks per min/min)* (mindmg+maxdmg:2)
where mindamage is half of the maxdamage on sib weapons and you need to figure out a skillmodifier for the mindamage you do with non-sib weapons. (for example hitability 3.0 is about 0.67*mindamage)
Using this formula you get the actual damage you do (not counting criticals or misses). The nice thing about this formula is that fast reloading non-sib weapons actually come close to sib weapons in terms of damage per second. You can compensate your meagre mindamage with a higher reload.
for example:
shriek combat 26 dmg 19,9 dmg/s cost 6,43 per shot avdmg/s 13,29
korrs h380 24 dmg 17,6 dmg/s cost 6.12 per shot avdmg/s 13,19
where avdmg/s on the shriek combat is with a hitability of 3.0 so 0.67*mindamage
What I am trying to say is.. there are still choices in the non-sib area.
When you get a gun with a nice fast reload, low ammo consumption and a good economy, you can still compete with the sib-weapons, because: you do not pay any markup once you have the gun
There is one simple rule to follow: pick high reload, low ammo consumption, high economy and you still keep (roughly) on par with the amped opalo solution, using sib or non-sib. Ofcourse sib is preferable always, but it all depends on the markup.
here is a post where i go deeper into this subject:
Life after Opalo
Using the justifier mk2 is not a fair comparison.. because it simply is way more expensive then the opalo/amp ever was.
