I'm pretty sure he was just indicating the dps numbers were running simulationcraft with those, not that you have to have them on and test. He was just trying to do a min/max comparison. Since they are within 100 dps of eachother, I am pretty sure that is within the variance for the RNG on the Gurth proc in the off hand. Basically, not noticably different either way. The whole point of simulationcraft is to "test" more extensively than you realistically can in game yourself. The simulations it runs are generally accepted to be accurate enough that we rely on the results. Additionally, by being able to simply choose 1000, 10.000, 25,000 w/e iterations, you can eliminate statistical anomolies better than you can on a target dummy.
