We all have days like that. Once I sat down the night before a 50 target tournament and fletched up 2 dozen cedars. At the shoot the next day, you could track my progress around the course by all the red and orange feathers and cedar shrapnel laying next to the trees. I had to refill my quiver when we took a lunch break! Went home from that shoot with 3 arrows left out of 24.
You see? You didn' t do as bad as you thought.
By the way, that was also the last time I shot that 120 pound longbow at a tournament. Never shot over 65 pounds in tournaments after that.
If you' re shooting good in practice, then you just have to remember to keep relax and enjoy shooting. That' s really what it' s all about. Trying too hard to shoot well and getting tensed up is the #1 mistake most new tournament shooters (even scruffy old veterans, for that matter) make.
