If you are happy with it then don't mess with it. I certainly wouldn't waste the time shooting it thru paper. What if it shows a tear, are you going to try and fix it possibly affecting how your fixed blades shoot? Are you going to hunt or shoot paper?

If anything I would move back to a farther distance and see how the fixed blades shoot, if they change or something you might want to do some touch up on them. However if they fly good at the distance you intend to use them at I would leave it alone. Some times you get lucky and things work great right of the gate. Depends on your form, release and how well matched the arrows are.

I would concentrate more you your shooting skills and not worry about the tune of the bow. Tuning is actually a minor part of being able to shoot well.
