Guys
I don't buy into the notion of ignoring nock position when bareshafting and here's why.
When I bareshaft, I do it out to 30 yds. I start close, maybe 7-8 yds away. As I have a long (29+) draw, I'm usually starting with a full length shaft. That means my first shots are generally with a shaft that's too weak. A weak spined arrow coming out of a right handed bow will dart to the right and will impact the target as such, with the point stuck to the right and nock to the left. As you shorten the arrow, it will gradually begin to stiffen and thus straighten it's flight path and be straighter in line when it impacts the target. As that occurs, I start to move back, first to 10, 15, 20 and finally 30 yds. When all is well, that bareshaft will hit where I aim, and impact the target dead straight, just like a fletched shaft. So I don't see how folks can say to ignore where the nock ends up when they are trying to tune a bareshaft to match their bow.
What Rybohunter described above is exactly what one would expect. He removed point weight (ie... made the spine higher) which made the arrow impact even more to the left (nock right). To fix the problem he needs a lower spine (more weight at the point or a weaker shaft). I would argue that I could have a dead nuts perfect release but if I'm shooting shafts that are too weak, they will impact to the right of the target, nock left. Likewise if they are too stiff, they'll impact to the left of the target, nock right.
