Semantics if you asked me....

Unless that animal is standing still for a long time...your "spot's" gonna have to change. That good spot when he was 4 steps back there might not be the right spot when he is wher ehe is right now.

I agree that knowing the path your arrow is going to take through that animal is VITAL information. What better way to imagine that than having your pin on the animal and adjusting. That's the ultimate in the angle. It's a straight line from your pin through that animal (taking into sonsideration the angles).

The "spot" is constantly changing....unless that animal's standing still.

Wherever my pin is at the given time is the spot. I can't determine said spot until I get ready to pull the trigger.
