Bkupris, I agree and disagree. It has been my experience that I get the best grouping when I have bare shafted by bow for tune. In most cases, I have nothing to do beyond that point. I do believe that for those who can't keep it together to get that 50 yard bare shaft tune, the following will fill the bill. This is where I agree with you O great one.
Once you have achieved the best bare shaft tune possible, you should shoot your broadhead tipped arrows with your field points. You will be attempting to get them both to hit at the same point, you will be making this adjustment by moving your nocking point, up or down. Shoot these arrows for group over the distances that you will be shooting at game, it is a waste of time to shoot out to fifty yards here, after all we are doing this for hunting. You will be amazed at the confidence you will have when you see what you and your bow are capable of. If you broadheads are hitting below your field points, you should lower your nocking point a 32nd at a time.
You will find that once you have found the right arrow shaft during your bare shaft, it is wiser to adjust for left and right shooting by dealing with your brace height. You might be suprised to learn that you bow shoots a little more silently when that "sweet spot" is found.
