The Coverage Index (CI)
The Coverage Index is the scale restorers use to describe how much skin coverage they have, from a tight circumcision at CI-0 to full coverage with generous overhang at CI-10. This is the scale the Forestorers journal uses for your profile and progress tracking. Match yourself against the drawings; when in doubt, trust the picture over the words.
CI-0 路 Extremely Tight
Very tight circumcision. No slack skin at all; erections may feel tight or uncomfortable.
CI-1 路 Tight Cut
Very little slack skin when flaccid. A typical tight circumcision.
CI-2 路 Average Cut
Some skin movement along the shaft, still well short of the glans rim.
CI-3 路 Loose Cut
Noticeable slack; skin bunches up behind the glans rim. A loose circumcision.
CI-4 路 Intermittent Rollover
Skin starts reaching the coronal rim when flaccid. The first big milestone.
CI-5 路 Permanent Coverage
Skin rolls over the rim; less than half the glans covered when flaccid.
CI-6 路 Majority Coverage
More than half the glans covered when flaccid.
CI-7 路 Full Coverage
Glans fully covered when flaccid, though the shape may still show through.
CI-8 路 Flaccid Overhang
Full, reliable flaccid coverage; some coverage begins to hold when erect.
CI-9 路 Loose Overhang
Full flaccid coverage with overhang forming; near-complete coverage when erect.
CI-10 路 Generous Overhang
Full coverage flaccid and erect, with overhang beyond the tip.
Most restorers start somewhere between CI-0 and CI-4 and move roughly one level per one to two years of consistent tugging. Progress this slow is invisible without records, which is what the Forestorers journal is for: log your CI, sessions, and photos privately in your own browser, and this same reference chart is built into the entry editor.
