well in a normal week i probably practice maybe once a week. i should pratice more, but after a day of working i am not ready to practice. well for me i have noticed that the more arrows that i shoot in one practice. that i do seem to do a little worse. my only thoughts are the your muscles may be getting a little tried. so relax for a day and try again.
I find the same thing. I usually try to get out once a week in the off season, then 2 or 3 times a week for the month before the season begins, then once the season is in full swing, im back to once a week. That is always on Sun. since in VA, you can' t hunt on Sun. and the rest of the week, instead of practicing, I hunt.
