Confusion with Extender And Stretches

Hello guys. So, I have been doing s2s for some time now and in my limited knowledge it only aids in the BPEL growth. I am 5 inches NBPEL and want 6 inches NBPEL. Bought my male edge extender and its been 3 days and I did 3hrs/day by removing the noose and replaced it with velcro. The traction was 1200 grams.

Now the confusion is since I can put more force by doing s2s, will the extender result be hindered since there is less force but long hours. I don’t want to condition my dick in a way that the extender would not work. What should I do?

Also, NBPEL is about tunica stretch(if I am right), shall I be doing the stretch where I hold the base of my penis with one hand and stretch with the other making the tunica stretch instead of the ligaments? I have been doing s2s for 2 and a half months now and I also do V stretches with them.

PLEASE HELP
