Yeah it is up all the time. I noticed it when I was using SoV. The 5 stack tick, 5/5 bonus tick, and judgment all seemed to be critting a bit more then usual.
I will see what I notice in raids this week. Eternal Rest has never dropped for me and I gave up on it. Our ret pally does Crusader so Zeal is useless for me. I remember reading a thread about the new badge one. When the numbers were crunched the boosted threat was very minimal. It makes me wonder if the extra 52 crit is more of a threat boost then the the badge one.
I am no math wizard so I don't have the number crunching done. But it is up all of the time if you judged anything on the mob. I am always on wisdom duty...after the initial judgment, anytime I hit the mob and it refreshes, the 52 crit buff refreshes on myself.
