Take a piece of electrical tape 5 feet in length and stick it to the floor in your house somewhere the wife will not move it. Everyday for a month set up to the tape with your putter and walk your eyes down it (toward the hole) and back to the putter face. IT MUST TAKE AT LEAST THIRTY SECONDS. Now read all your practice putts for the next month. After thirty days you will know if you are linear or non linear.
This is great stuff here.
As seminal material in The Lab, it may prove to be even greater.
