Absolutely.. some days not too often I just wanna unstring the darn thing and throw it like a javelin at the target! Maybe that'll hit the mark! Sometimes if I see this happening, I am aware enough to know to slow down, and go through the shot sequence mindfully. I always start practice at 10 yards, form first for 20 twenty arrows, then I go for practicing at further distances and accuracy. Seriously, some days you get the bear. And some days the bear gets you. If your form is correct. Then it is probably mental... stress, distraction, whatever.. inability to focus correctly. The mental aspect is tougher than the physical, if you are lacking confidence and uncertainy of hitting the target, then you are already setting yourself up to miss. Sometimes it's best to walk away and clear your head for a day or two. Then come back fresh. 10 good arrows is a whole lot better than 100 bad ones.
