I can't speak for these other peeps and it's just my opinion, but I think it does.....why train ur brain to spot at dots? Excluding butternuster shooting at the spots on fawns hehehe....none of the animals I'm trying to kill have dots...legal deer can't have spots here.
Also helps to practice for the ¼ to and ¼ away shot angle and shooting for the exit on elevated shots...
When tuning the bow and tuning the arrows I shoot block but for sighting in the sight and practice for hunting the 3d is more realistic of what it's really gonna look like.
Maybe it doesn't actually help but it's more fun....I can't stand shooting at set distances like at a range
Edit: oops too slow
@gcr0003 beat me to it
