In a perfect would I would like to see my nock travel the full distance of the power stroke inside a tube not much bigger than the nock and never touch the tube.

With that said, I challenge this team on this forum to discuss and find a way to measure left to right string travel.

Whether you know if or not must of our Martin bows have a lot of left and right string travel. In the neighbor hood of 3/4". This is part of the reason why at the static position the sight pins are generally a fair amount left of the arrow shaft. (Right handed speaking).

The TRG has helped this problem a lot. How much??? I know the TRG tunes a ton easier. I want to measure it.

I have some ideas but really hard to explain.

OK archery Engineers let me know what you think.

Thanks
Gary
