Good for you, you picked up on the very reason for this. Temp items can come in droves, but there will be times when it won't thus making your statements false since they too are subject to situational exceptions. Temp items are not all encompassing thus become an inconstant variable on damage that places biase on otherwise standard data.
All data and calculations I performed were base statistical data with no other outside variables that couldn't be considered "constants." You based all of your argument on highly situational and biased empirical data to argue against data that can apply to any situation since it is virtually devoid of inconsistencies.
Plainly put: CdC is powerful, but alone it is not "that powerful" within constant data calculations to make a WoE weapon push a relic out of 2nd place primarily due to your biased data. It would be like a doctor performing a drug test on 8 individuals and giving 2 out of 4 of the actual test subjects something more to enhance the base drug in testing for favorable outcomes. Obviously the 2 getting the supplements will do better than the 2 without. Better context would be a war saying they can put out insane damage all the time based off sample data taken during 2hour and full buffs. Since all the statistics are not constant it is inaccurate data.
From temp items you are getting increases to your base (constant) pdif, acc, fstr, and dDex values which are not constants. Applying constant data to constant data it has been proven that VWNM do have inflated values on top of other additional constant values such as -mdt/pdt, evasion boost, accuracy boost, and other passive traits that are always active.
