Trading a few hundred crit for a few hundred mastery just isn't going to change your DPS by much. It's small enough to easily be lost in the noise of RNG, fight mechanics, and execution.
But still, you may be right. As I said, evidence trumps theory. Gotta account for all the variables to figure out what the evidence actually says, but evidence trumps theory.
IMX, Simcraft is generally pretty reliable. Not perfect (that's why they keep releasing updated versions, after all), but better than just guessing, and much easier than trying every possibility by hand. But yes, still, it is just a tool. If Simcraft tells you to do something, but that isn't working, don't do it. This doesn't mean you should disregard everything Simcraft says; it just means that you should recognize that it is only a third-party tool intended to help figure things out. It can't and isn't supposed to replace your brain.
