Atlasman, try not to take him wrong. All of us have been NUBBED at least once during are past posts. Nub is just short and too the point. []

I do agree that the easton tuning guide is a very good reference if you NEEd to tune due to poor grouping, bad flight etc. but if you are already shooting good dont mess with it like I did. I was grouping very well and my arrow flight looked good but I decided to check the paper. My arrows were showing about 1/2 nock high. I took out the easton guide and did everything I could and ended up with worse flight and groups went skewy. I moved everything back to the original position and all was well again. Remember, you dont need bullet holes to get good flight and good grouping. There are too many other factors involved.
The biggest problem, that I have found, to creep into your bow tune is a nocking point movement. String stretch, serving seperating, etc. seems to wreck havoc
on a bows tuneup more than anything. Get a bow square and check your nocking point very often. Once a bow is tuned, this seems to be the biggest problem . Keep it checked and adjusted and you shouldnt have any problems. Im in the same boat as you with this tuning stuff. Im sure someone else can answer your question with alot more detail.
