Forum:How Do I Determine What Weapon Is Better?

What I have been doing is keeping one weapon of each type (including one revolver, one repeater)and just selling everything else. What I used to do to test which weapon was better was I simply multiplied the fire rate and damage (getting the damage per second) in each gun and whichever had the highest, I would keep. I then noticed two things wrong with this method. First of all, burst combat rifles do not work for this as their fire rate only takes in consideration how fast the burst speed is, and doesn't add in the delay between bursts. Second, I noticed that some weapons that had a higher number than another weapon did worse in combat than other weapons, because those other weapons had elemental damage. I have several questions on this topic. First, is there a way to figure out the "actual" fire rate of a burst weapon. Also, is there some sort of new equation that is more improved than mine that some how adds elemental to find which weapon is stronger. Lastly, I'd like to know what methods you use to pick which guns you wield. Thanks!
