How is that silly? While yes its not good to practice until you develope bad habits, 50 shots a weeks is less than 10 a day. Everything I've read talks about shooting until its second nature. 10 shots a day is not going to make something second nature. How about blank baling just to work on release? I'd venture to guess most people are going to advocate much more than 50 arrows a week to develope a compitent level of shooting.
