well ususally at 20 yards i don't shoot at the same spot, don't want to keep on refletching or putting on new nocks but i thought i would be safe at fifty. my groups have definately been getting tighter since i did walk back and broadhead tuning. its nice, all my fixed blades (thunder heads, muzzy's wasp's and some unknown old one) are hitting the same as my field points....all the way out to 50. that all the room i have in my backyard, i will have to go to a field to dial in for 60 but i'm not in a rush.
