Designed to cover all stages of progress between grower and shower and fix key issues with the current system. The Coverage Index is used to determine how much foreskin coverage covers the glans.

CI-0 Bleeding when erect. Painful erections. Curvature that straitens after restoring a little skin.

CI-1 No loose skin while flaccid or erect. Like a broomstick.

CI-2 While flaccid there is some loose skin, wrinkles. The beginning of skin mobility. Glide action. From here it only gets better and better in terms of glide.

CI-3 While flaccid some skin touches the corona ridge. Lots of wrinkles and skin seems bundled up near the corona. This is the first hump.

CI-4 While flaccid some skin starts to edge over the corona. Depending on flaccid state it may retract back to CI-3.

CI-5 While flaccid, skin starts to cover half of the glans. Less likely to retract but can.

CI-6 While flaccid, skin covers about 3/4 or more of the glans.

CI-7 While flaccid, the glans completely covers the glans and partly shows if look underneath.

CI-8 While flaccid there is a small amount of overhang.

CI-9 While flaccid there is a good amount of overhang.

CI-10 While flaccid there is a substantial amount of overhang.

ECI-5 While erect there is a visible crease. See image. This is the second hump. If grower, it usually happens around CI-8. (Similar to CI-3)

ECI-6 While erect, foreskin covers starts to edge over the corona. (Similar to CI-4)

ECI-7 While erect, foreskin covers half of the glans. (Similar to CI-5)

ECI-8 While erect, foreskin covers 3/4 of the glans or more. (Similar to CI-6)

ECI-9 While erect, foreskin completely covers the glans. (Similar to CI-7)

ECI-10 While erect, congrats first of all! Foreskin overhangs while erect. (Similar to CI-8)

PCI Precise CI-Scale:

CI-Scale: NSFW click image to view.

The PCI-Scale is made to cover every stage of coverage weather grower or shower. More than other scales, the PCI-Scale shows more similar progress made between a shower and a grower especially once at ECI-5. Keep in mind, foreskin restoration is not a race but more a personal marathon.

One example of how to use this scale. CI-8/ECI-5: Meaning flaccid at 8, and erect at 5. Based on the images seen on the original Coverage-Index-Scale. Click image to view CI-Scale and what these number attribute to.

Even more precise put G for grower and S for shower. Example: GCI-8/ECI-5: symbolizing a grower at flaccid ci-8, erect at image 5. More useful at the beginning stages(CI-0 through CI-7).
