This article measures the Shift as being 9mm higher in the heel. That being said, the Aattacks have more ramp angle than Squires, for instance. IIRC the Aattacks are about 5mm higher in the heel.

I’m not sure you can compare the numbers of that article for tech bindings with an alpine binding delta.
Quoted from article: “Know that due to how tech bindings such as Dynafit function, the spreadsheet numbers are not the binding delta/ramp as you would measure with an alpine binding. Instead, they are the distance from ski top up to the center of tech binding pins. Thus, the numbers are for COMPARISON between different ski touring tech bindings. (We do have some angles calculated in the spreadsheet, for specific boot sole length and with a few mm added to the heel fitting height to make the results more reflective of real life.)”
Although with them measuring in this way, makes me wonder how they measured the Kingpins and Shifts since they don’t have pins for the heels.
Considering I've been under the impression that heel lift has always been bad for me.
Keep in mind heel lifts inside the boot are different than ramp/delta on the boot sole. A heel lift inside the boot opens your ankles and keeps the forward lean the same. Additional delta in a binding will keep your ankles in the same position, but will increase your forward lean.
