I'm quite surprised you're putting so much effort into tuning the fit. Has your end goal changed?
Jen was trying to wear it lower
If the front shield and cable hang down below, it will need to be tightened so that it sits a bit higher, otherwise it'll chafe terribly.
Jen getting there... bends easy enough sorting out where to bend is hard
Wear it for some time and move around. Remove it. If you see a red spot, bend a bit more curvature into the band on both sides, that will reduce the pressure on that spot.
