No, you cant make adjustments to your sight while your shooting the tournment. But you can make adjustments to your buddies sights. Its best to do it when they are pulling arrows. You can also adjust the poundage on their limbs if you are fast enough. Let them shoot a couple targets after your adjustment and if it dosent correct their problem make another adjustment in the other direction. The important thing is not to let them know about it. They wont ever know how good of a friend you are.
