Plateau: Foreskin (cut) is the limiting factor in gain?

I’m cut and gained about 1/4-3/8” BPEL from pumping (cycling / milking the tube) and dry jelqing. However, I noticed I haven’t gained much for the last couple of weeks. I suspect my cut foreskin is holding back my gain as it looks real tight during a hard erection and there’s not much room for it to stretch any further. Any suggestion?
