Ethereal Weapon DPS

How is the DPS of an Ethereal weapon calculated ?

I have the Barctu’s with +94% Dmg, +97 Dmg and +100% Dmg.

The lowest DPS has the +100% Dmg weapon.

How is that possible?

There is no attack speed on it, all at 1.40 aps and there is no affix weapon rang dmg on it.

What determines the DPS on the weapon except the +X % Dmg?

Apparently there’s a hidden damage range. It may be the damage range / dps you’re able to see on the Ethereal weapon before you identify the item, but I doubt that’s it. I suspect it’s more along the lines of the Elemental damage range that are on regular weapons but it isn’t shown. shrug?
