I have always assumed so. I break in a new string by leaving it strung overnight, shooting about 100 arrows, then overnight again.
I then use masking tape as my nock point while i figure out brace height. Masking tape is pretty stable while shooting, but super easy to tear off and do over should the measurement change.
I then tie on a permanent nocking point, but I don't try and tie the type guys talk about that will screw up and down the string. I want my nock fixed and permanent.
