That depends on what type of stringer you have and what type of pre stretching you are doing. You could pre-stretch manually by wrapping a set of starring around a pole and pulling on the ends to remove coiling. Or you could use a pre-stretch on some electronic machines. When pulling tension two times (or more) on the string on a lock-out machine you will see a difference. If you are pulling tension two times on a true constant pull (some electronic machines are not true constant pull) you will see less of a difference if any. If you go through the process of pulling two times on a true constant pull then you will be pulling the string for a longer period of time. If using a constant pull and you increase the time you pull the string you increase the stretch. Even though the tension is the same longer pulling times produce a stiffer string bed.
