Flurry uptime simulatorIt's been a common practice, when calculating the exact dps from Flurry, to assume thay 'oh hell, it will be up 100% of the time anyway'. This tool was started by Beornoth on EU forums and later adapted to my Sword vs Axe calculator. Some people were surprised that Axe spec don't benefit that much from Flurry as it might seem, and more then that, it turns out Sword spec benefits from flurry a lot. This little tool should help you understand how crit rate affects Flurry.
