OK, give up the damage increase stuff guys. The only thing you should be concerned with is HASTE, which translates to Delay Reduction, AKA a Faster Swing. If you guys would stop belabouring and clouding the HASTE issue with Damage vs Delay rhetoric, it would be easier for people to decide what items they want to use.
It's put up or shut up time. I have parsed my log file. IT DOES MAKE ME SWING FASTER. Any extra damage beyond normal is BECAUSE YOU GET MORE SWINGS! Get off the more damage! Prove to me that it makes the weapon DIRECTLY do more damage. I am truly getting tired of people confusing the issue by saying it does more damage without making your weapon delay faster... More swings in the same amount of time PROVES THE WEAPON GETS FASTER!

It is a HASTE Item. It makes you SWING FASTER. The rest is dependent on whether or not you actually hit the creature in question.
