I know I will catch some slack with this one. I don't think 3" groups at 25yds. are acceptable according to my standards. You should be busting nocks at that distance. In my opinion 3" would be acceptable at 40-50 yards, even then with practice you should be robin hooding arrows. I can't shoot more than 2 arrows at the same target dot with out busting them out to 35 yards. Out past that I can shoot more arrows at the same target dot and not break as many. If I were you I would go buy some of the orange 1" target dots and practice with those. Just stick them to your target and shoot away, you will be surprised how many knocks/fletchings you ruin.
