Out here in the west we only count one side of the rack,
But that can be expanded upon. If the count of points is different from one side to the other. As with this 5x6:

(His left side eye guard forks, more than one inch each tine)
But we don't call it an 11 point buck. It's a 5x6. If it were only five to a side, then it's a five point. An average or above average mature buck of Whitetail, Blacktail or Mule deer.
I've shot several 2x3 Blacktails. Not a true 3 point. (each side), But then again, not a fork'ed horn.
Here in Washington, an antler must be at least an inch long to be counted. A spike, (not a button buck), must have at least one tine more than one inch. (Where spikes are legal to hunt)
This is for Deer or Elk.
We have several game management units where hunting is restricted to minimum point total per one side of rack. A spike Bull Elk, must have only one beam on either or both sides, no forks anywhere. And there are 3 point minimums for Blacktail or Whitetail or Mule deer. Heck, sometimes you can't see half of a rack in dense cover on a Blacktail let alone the whole thing to count points before you squeaze the trigger. Counting one side works out west where we hunt on the ground with the critters. Not generally from treestand. Not on soy farms. Not around deer feeders!
Oh, whoops, I didn't mean to vent.
