How far do you stand from the target when bare shaft tunning? I just replaced my rest and strike plate and need to retune because the thickness has changed.

I stand back 20-25 yards. If you have way less room you can paper tune. Both work.

20-25 yards is plenty.  Many olympic shooters do it at 70 yards or more.

I start up about 15 yd. and work back to fine tune.  25-30 yd. to fine tune for me.  If you have a foam target you can shoot closer and see how the shaft hits until you get close to tuned.  Paper is also real good and can show me stuff I may not see with a bare shaft with HFOC arrows.

If I am not sure where I am at I start at 10 yds until I know the arrow will at least hit the target.  From there I start backing up to 25-30 yds as my tuning gets closer.  40-50 yds is for fun when I have an exceptional shaft just to see it happen.  Bare shafts can be very hard to find in the grass.

Ten yards or less. The shaft is going to show the problem as soon as it leaves the bow. If it shoots perfect when it comes out it will be fine down range. And I shoot it through paper so you can see which way it tears to show you what the shaft is doing.

I'll start at 10 yards at first to make sure it will hit the target and then move back to 20 yds.

In the past I could do it out to about 50 yards but if I can get a bare shaft to fly straight at 30-35  it seems like that is plenty. I generally start at about 5 yards to make sure the nocking point is right then slowly work back making adjustments to my plunger and centershot as needed.

This will give you some additional info

That is a great write up. I think i am going tp give that bradhead tuning a try.

Referring to the broadhead tuning section, what is considered a "wide" broadhead? 1 1/8" or 1 3/16" or larger

I am wanting to shoot the 125gr Landsharks or the 125gr 3 Blade Woodsman Elite. Are those considered wide?
