You can use the top edge of the dot to make a more precise shot.

The main purpose behind a red dot is to speed target acquisition. In that role, the cheek weld and position of shooter's eye in relation to the center of the ocular lens is not critical. However, for that rare time when a more precise shot is required, it can be done and cheek weld is important.

Which brings us back to the purpose of this thread. A shooter could use a 1/3rd co-witness because a loose contact with the cheek could provide very quick acquisition. Then when a more precise shot is required, knuckle down and make a harder cheek weld, which would potentially put the shooter's eye lower in relation to the optic.

I agree that no one would pick a red dot primarily for precision shooting. But that doesn't mean it can't be used for a precision shot.
