I'll be new to bowhunting this fall and have been practicing since April with the bow so my opinion does not come from a lot of experience.
My thought is if that is what you are shooting consistantly from 25 yards from the position you will be shooting, with the clothes you will be wearing then it is acceptable from 25 yards. I can only relate it to hunting with a rifle. I get 2 inch groups consistantly at 100 yards and 3 inches at 150 using the positions and rests I will have in the field. Since a kill zone on a deer is at least 3 inches I consider myself good to 150 yards but not beyond. Mainly because I've never practiced more than 150 yard shots. Again, not alot of experience but it seems to make some sense.
