RE: 3rd plane sight adjustment
Ok Dan.....this is pretty rudementary, but you'll get the idea, I think.
Picture 1 is a level, sitting perfectly level to the ground. The blue circle represents the bubble. Now, roll that cube forward, on the pink line. If it doesn't roll perfectly level, (3rd axis) the bubble will look like the 2nd picture. You will then correct the level, causing the bow to be canted badly, and miss right/left. Hope this works, my paint skills suck.

RE: 3rd plane sight adjustment
This is what happens if you set up square to the sight bar and the sight bar is not square with centershot(arrow path)
Doing either one of these will set the 3rd accurately.Spelling correctly obviously isn't necessary to understand this.

RE: 3rd plane sight adjustment
I think I get it now... I just had to imagine playing around with my sight level. Let me know if this is correct;
Assume first of all that the 2nd axis is set properly.
If the bubble level is perpendicular to the riser, and the riser is perfectly vertical, then aiming up hill or downhill will result in a bubble level that reads "level" if the riser remains perfectly vertical.
However, if the bubble level is NOT perpendicular to the riser, then aiming up hill or downhill will result in a bubble level that reads "not level" when the riser IS perfectly vertical. So in essence, your bubble level lies to you on uphill or downhill shots, resulting in left - right misses.
Since riser torque is introduced at full draw, you need to set the bubble level so that it's perpendicular to the riser when at full draw.
Is this right?
