If your form is causing a good tear at one distance,the tear will change at another,so you will get a false reading.


If you get a consistant tear at different distances,then you are probably good but if the good shooter gets a good tear with an arrow that is "supposed" to be the properly spined arrow,that is probably pretty close to correct.

My program is showing you are way underspined with THAT bow.

I doubt that you willget a good tear at more than one distance from the paper.
