Not trying to be snarky, but a 150 DPS swing from a single relic seems implausible. How many tests did you do? What is the standard deviation of the two DPS values you measured?
Right it does sound a bit extreme after I think about it, while I did use two separate Relics (Proc on one parse and Static on the other). There are probably several variables that I changed to affect the damage increase, talents (adding accuracy), and I think standing behind the dummy helped too, I noticed fewer and fewer dodges from the dummy. I'll do some parsing again today, same spec, positioning, just different relics and post links.
