Rake clipping is very liberal and you can call it accounted for, I was talking solely about Rip. I tested with DoC, I believe. Also, it was with PTR Renataki's which is a lot different than live Renataki's when it comes to this discussion.
Like I said, the problem is in order for it to not be a DPS loss, you have to conditionalize it with so many things that it rarely happens. After accounting for these things, the number of times where you can wait long enough to gain more than 1 or 2 stacks is very low, something like once every other fight.
If you keep waiting after OoC procs, it's a loss. If your TF expires while you're waiting, it's a loss. If your 4p bonus expires while you're waiting, it's a loss. If you push back TF's CD even a couple seconds, it's a loss. If you do it during Berserk, it's a loss. And on top of all of this, the number of seconds you can wait is restricted by your energy pool and your energy regen.
There may also be some other conditionals I had in there that I am forgetting about. By all means, if you would like to try and see if you can make it a DPS gain in SimC then you're welcome to, and I'd be happy to be wrong, but I spent enough time on it that I'm fairly convinced that it's not possible to make it a gain in the sim, at least not a significant enough one to warrant putting it in the action list.
