String loop nock point?
 

I want to install a string loop on my bow string and would like to know how you determine your nock point with the string loop?
Without the loop you draw under your arrow and with the loop you are drawing in the center of the arrow so how do you determine your nock point?

the top loop is the same as a brass nock point for measuring.
With my bowsquare, I use an arrow nock in the loop (on the string) and set the center of the nock square with the string to start (makes the TOP of the nock about 1/8" high as is normally suggested for a starting point with brass nocks.

Your old nock point is a good starting point.

You may have to adjust it a bit because of where the pressure is being applied to the string.

Put it on and tune it up anyway.
