Figuring Out Weapon Damage

[guineapig]

I read somewhere that this is the formula to use when rating the value of a weapon
(excluding haste and procs obviously).

(Dmg*2)+1 / (Dly/10)

Blackened Alloy Bastard Sword (weight 2.5)
(24*2)+1 / (39/10) = 49 / 3.9 = 12.56

Enchanted Fine Steel Bastard Sword (weight 8.5 - Str +7 net weight 1.5)
(note the same damage/delay ratio as a Dark Reaver)
(20*2)+1 / (42/10) = 41/4.2 = 9.76

Jade Reaver (weight 12.0)
(23*2)+1 / (40/10) = 47 / 4 = 11.75


If I'm reading this correctly, BABS is a much better sword then even a Jade Reaver... is this true?

Here's A few more comparisons with tougher to get swords (big quests or raid only)

Ghoulbane
(15*2)+1 / (34/10) = 31 / 3.4 = 9.11

Efreeti Zweihander
(24*2)+1 / (45/10) = 49 / 4.5 = 10.88

Ashenbone Axe
(24*2)+1 / (42/10) = 49 / 4.2 = 11.66

Razing Sword of Skarlon
(25*2)+1 / (40/10) = 51 / 4 = 12.75


I know that some of these weapons aren't in the game yet.
When I started writing this up I was under the impression that the Blackened Alloy Bastard Sword was already in (it isn't [You must be logged in to view images. Log in or Register.] ) so I was attempting to see just how good it was compared to other present and future 2-handers.

Point being, I'm not 100% certain what that calculation does but it seems like a pretty good indicator of general value based on damage.
