Default Forced Erect Coverage

There are lots of ways to declare your restoration a success, but I think the most dependable way to know you're making progress is to measure Forced Erect Coverage. I'm sure I didn't invent this idea, but here is a mathematical approach which I believe to be my own innovation.

Forced Erect Coverage

An indication of how much slack skin is present. It's just the percentage of your glans length that you can force skin over while you're erect. To measure, get erect and force the shaft skin away from your body, toward your glans. FORCE the skin over the glans (but not to the point of causing pain). Measure the length of glans that is still showing on top (from the tip back to where the skin rolls under). Then let the skin roll off the glans and measure the length of the whole glans on top.

FEC = (1 - (glans showing/whole glans))

The number is a percent. For example, with 1" of glans showing, and 1.5" for the length of the whole glans,
FEC = (1-(1 / 1.5)) = (1 - 2/3) = 1/3 = 33.3%

If you can't force the skin to reach the glans then FEC result will be negative. For example, with skin forced forward but falling 0.1" short of reaching the glans, and 1.5" for the length of the whole glans, the glans showing is 1.5 + .1 = 1.6 and
FEC = (1-(1.6 / 1.5)) = 1 - (16/15) = -1/15 = -6.7%

Once it's possible to cover more than the whole glans, the number includes the distance past the glans as "negative" glans showing. You may need a pencil or other slender tool to sound the distance from the end of the bunched-up skin to the tip of the glans. For example, with skin forced 0.5" past the glans, and 1.5" for the length of the whole glans,
FEC = (1 - (-0.5 / 1.5)) = 1 - (-1/3) = 1+1/3 = 133.3%

A typical foreskin restorer can add at least 1 mm per month to the amount of glans that can be forcefully covered with skin while erect. Lots of guys progress faster - the 2010 controlled trial participants averaged 3mm of improvement per month while tugging 11 hours per day. If you're just starting out, take your before pictures and measure FEC, but wait until you have been using a consistent regimen for a week before taking your official baseline FEC measurement which you will compare to your monthly readings.

So let's do some real-world cases:

Here's a glans that measures 39mm

With the skin forced up while erect there are 14mm of glans showing

So the forced erect coverage is (1 - 14/39) = 64.1%
- - - - -
In another example, say the same man's skin can instead be forced PAST the tip. A blunt tool can be used to sound the depth within the skin tube until the tip of the glans is touched (of course be careful nothing enters the urethra).

The tool is withdrawn and the distance from the observed coverage point to the end is measured at 24mm

so the FEC is (1 - (-24/39)) = 161.5%.

Note that in the above photos, the hand forcing the skin is positioned to allow an example measurement to be photographed. In practice that hand would be gripping closer to the end of the skin tube.

On the matter of accuracy and consistency of measurements, the tricky parts about FEC are being FULLY erect and forcing skin AS FAR AS it will go without causing pain. The pain thing is for each individual to gauge. As for full erection, if you repeat the measurement a few times in the span of a couple minutes, the largest glans length you get would correspond to the fullest erection. The largest "glans showing" number that you get while rolling skin up would also correspond to the fullest erection (assuming you're forcing your skin equally as hard each time) so use the largest numbers you would record on a certain day in all cases.

To re-iterate, I suggest you FORCE the skin over the glans with no regard at all to where the skin came from or how hairy it is, because this technique of tugging just short of the point of causing pain is the way to get a reproducible measurement.
