Leaf is a compact hatchback, whereas Model X is an SUV. A better comparison would be Leaf and Model S, a sedan, which is rated at 241Wh/mi (and can reach this in actual use[0].)
Perhaps, I wasn't clear, but I was comparing to the 300 Wh per mile rating claimed for the Leaf upthread (I haven't looked it up for myself). I am comfortably beating that in real world use.
Edit: the point is that it is not clear that Tesla is much more efficient which was the original claim at the start of all this.
