I think mine is on the very tight end of the spectrum. I never get skin rolling over the edge of my glans, not even when super soft with shrinkage from the cold. I asked my doctor to give me a neat look that wouldn’t leave much loose skin behind the head when soft. When hard I have barely any movement in my skin and I cannot get it even remotely close to covering more than the edge of my glans and that with very hard pulling at it. I like it, I think it looks neat and the feeling of tight skin on my shaft when rock hard feels great. Contracting my pelvic muscles when erect adds pressure to the nerves around my scar due to the tightness of the skin and I feel it helps me stay harder for longer.
As for low/high, I don’t know. Probably somewhere in the middle. I have a V-shaped scar with the skin closer to the head on the ventral side (where my frenulum used to be), and quite a bit more inner skin left on the dorsal side (top).
