Correct, the others will be slightly off, but as you can see by how close the numbers are they are all really close.
It was zoomed 1 for AWP, but I've updated the output to show all zoom levels now.
CSGO scales the sensitivity to a 4:3 aspect ratio, so by setting the calculator to MDV 133.3333% (4/3) you will get the correct calculation regardless of your actual aspect ratio. In addition to this the scale is set to 120%, which is exactly the same as setting the zoom sensitivity to 1.2.
