Garage door adjustment question

I have a newer belt driven garage door motor/opener (chamberlain maybe?) attached to a two car, 4 or 5 (can’t remember) horizontal segment, metal residential garage door. It has the two tension springs on a long metal rod mounted on the wall above the door. When adjusting the door close limits in the motor/opener, should I set it so the door sets on the ground completely and “unloads” the tension on the rod that connects the top segment of the door to the belt drive (carrier?)? When I do this, and I press the button to lift the door, the opener kind of jerks on the door. That jerking is loud and seems like it would be hard on the door and opener mechanisms. If I set the limit so the door’s bottom gasket material just touches the floor, sealing against wind/water/etc, the rod connecting the door to the drive belt connector maintains tension. Is isn’t loose, so when I press the button to raise the door, it doesn’t jerk, but I’m wondering if that slight tension on the motor/opener via that connecting rod attached to the door, puts too much wear on the motor/opener as it sits for hours a day.
