I parsed a log of FRSS vs. FBSS the night I got the FRSS. I also ran another test the following night after the zone was reset and these where nerfed.
First, let's be sure that everyone understands that haste is calculated by the number of additional swing in a given time frame. To calculate haste:
A = # of swings without haste
B = # of swings with haste
Haste % = (B - A)/A * 100
Here is how I tested:
Test 1 - night it dropped
Frostbringer mainhand 22 delay
shield offhand
45 warrior with maxed melee skills for level
Target soul binder in FP (is immune to attacks) and turned on attack for 3 minutes apporimately then removed attacks with duplicate time stamps to accound for double attack.
no haste item - 180 seconds 80 attacks
calculated delay of weapon = 22.5 - pretty close to advertised
FRSS - 180 seconds 84 attacks
additional attacks over no haste = 4
calculated haste = 5% = (4/80)*100
FBSS - 181 seconds 96 attacks
additional attacks over no haste = 16
calculated haste = 20% = (16/80)*100 - pretty close to advertised 21%
The testing the next night was virtually identical to the previous night with the number of swings in a 180 second period being within 1 of the previous nights test. At best I would put this item as 6% (second test resulted in 1 more swing for FRSS, 6.25%). Anyone who says this is as fast as an FBSS or a Hangman's Noose has not done a controlled test and parsed the logs.
