HERO definately does not have a high LoD, at least on the surfaces I've tested it on. LoD isn't something that only has the higher limit. 1.2 mm should be fine for everyone and you can adjust to it no matter which direction you go as long as it stays in between some values. I would personally have a bit higher LoD in Logitech's 3366.
1. Go to "G Hub Settings"
2. it's in the "My Gear" Tab in Settings.
3. Click on your mouse icon.
4. Select a name for your mouse pad.
5. Start moving the mouse to calibrate it to the surface.
