If I understand correctly,you only changed the arrow speed so the source would have to change meaning you would have to shoot a speed bow and compare it to a slow bow with the same arrow.Or crank the poundage up or down.


For most hunters,we just change the arrow to change speeds and the difference would be even less than what Matt is showing.

Basically what this means is you still have to KNOW the yardage,a miss is a miss.


Oh, and Matt,Perry(Archers Advantage)probably has a few world records and national titles as well.


But,they are both great programs,I am actually thinking about investing in the OT2 myself.
