You have no evidence for the 11% difference. The fact that you have not presented evidence for that percentage after so long signifies that you're merely fabricating this number.
Xbox One being outsold in the US by 0.5 million (2.5 million vs 3 million), which is 20% of the X1's total sales. So yes, 20% is very significant considering that this is US-only. In Europe, it's being totally demolished, being outsold by a 4-to-1 ratio. If the X1 could not outsell the PS4 in March despite the Titanfall bundle selling for $449, what makes you think that the X1 will actually catch up? A $399 Kinect-less SKU is a total ripoff in comparison to the bundle. When subtracting the costs of the game and Kinect, the projected price of the standalone console is $289.
