I use Archers Advantage:
Dead on accurate when you use a scale and 3 different yardages like 20 yards,40 yards and 60 yards.
I just use a chrono reading and am usually perfect out past 70 yards.I need to fine tune the fps beyond that but am really close.
You need to know the sight length from peep at full draw,peep height(center of peep to center of arrow at full draw),speed,arrow weight,arrow diameter(already in program),fletching size.
Looks more difficult than it is.
I absolutely love Archers Advantage and I also love being able to make complete changeovers with my setup at night and go out the next day and be sighted in and shooting in a matter of minutes all the way out to 70 yards.In 1 yard increments I might add.
