Yeah the test needs a larger data set, and better precision and reporting. It basically says nothing at all. They need to use terms like average damage and average critical damage and give us all the variables and constants. The max and min may or may not be more important than the average. Also they are probably ignoring the fact they are fighting against a mob type that has a range of 4 or 5 levels.
I would be testing first on mobs around R50. You never know what scaling they might be doing still based on rank...after all these people complaining about difficulty of fighting low rank player vs low rank mob. After we establish what happens against equal rank mobs should we look at the difference on lower rank mobs.
