I agree with CBM SC, if nothing but your vertical is off, just get it so the arrow hitting where it was. It wouldn't hurt to learn how to group tune and put your setting through a real tuning process. Whenever anything has moved, I group tune.

I also recommend that you take some very careful measurements and write them down. This way, whenever something goes wrong, you can get very close without much trouble. Things that I write down: Axel to axel lenth, distance of string nock from axel, centershot position of arrow (vertical and horizontal).

After I get a perfect tune, I do one more thing to make it easy to get back to this position. I cut a small block of wood that fits against the riser, that is the exact distance I'm looking for. When a setting is moved, getting back to this exact position requires no more then a couple seconds.
