Some things you have to know beforehand
Everyone should know after they get up in a tree stand, how agile they are; how mobile they are; how much of the 360 degrees from the tree stand, they can actually use for a shot.
And getting the shot off timely, depends on how aware you stay of your situation. No one is perfect. And it's impossible to make comparisons.
If you weren't ready for a possible shot, you weren't ready. If you didn't know a shot was impossible for a certain position, you weren't ready.
