So I started looking at DPS trinkets and trying to model their DPS so that I could work out their DEP scaled values. Has anyone already done this?

In particular:
Hourglass of the Unraveller: http://www.wowhead.com/?item=28034
Icon of Unyielding Courage: http://www.wowhead.com/?item=28121

Now, for hourglass I modeled the chance on crit to add an average of 9-10 AP based on the time between procs people are reporting. This may be too conservative though. I would appreciate any feedback on that as I am not used to doing DPS modeling.

For icon of unyielding courage, I have no idea how to approach it yet.

Ideas?

Btw, this thread isn't about how DFT+Bloodlust/Abacus is the bettter combo. I am just trying to mathematically rate these trinkets. The aforementioned trinkets are much easier to model.
