I'd def take 6-12, that's legit
In terms of lower amounts I lean the way you've stated in previous posts there is a difference between 3-6 inches followed by rain or 50 degree weather the next day vs 3-6 inches of all snow that sticks around for a little while.
Also I really don't take the record very seriously because a lot of the area is already above the CPK number. It's just one spot.
