Quick Guide to Weapon DPS
By Drop.
Weapon DPS is calculated the following way:
(min. DMG + max. DMG) / 2 = average DMG
average DMG * attacks per second on the item = DPS
Or simply put together:
(min. DMG + max. DMG) / 2 * attacks per second on the item = average DMG
When you want to know the (physical) pDPS of a weapon you only calculate the physical damage of the weapon. If you only want the (elemental) eDPS you add up the DPS of all the elements. Overall DPS is the sum of the DPS types of the weapon.
Quality adds more phys DMG to the weapon by the amount of quality the weapon possesses. An expert dualstring bow has 39-73 phys dmg at base (56 average dmg). At 20% quality it would directly be 20% higher at 67 average DMG.
Example to calculate the DMG:
pDPS = (286+520) / 2 * 1.43 = 576.29
eDPS = (5+138) / 2 * 1.43 = 102.25
overall DPS = 678.54
As we can see this matches up when we look at the DPS numbers the trade website displays.
This can greatly help when you need to determine what weapon is better, how much of a DMG increase the other weapon would be or when you try to price an item.
