When you're sighted in correctly, your site is set to shoot the arrow high to compensate for gravity. So tilting the bow either direction should result in a slightly low impact. I would also think that since you are shooting "high", to compensate for gravity, your arrow would impact off the X in the direction of the canting. Does this make sense or am I completely off base. Also, I think the faster the bow, the less drastic the results would be.
