Assuming that skin tube growth speed is directly proportional to current skin tube length we can derive an equation for estimating the total remaining tugging time in years:

required_time (in years) = time_to_double_length * log2(goal_skin_tube_length / current_skin_tube_length),

where time_to_double_length (constant) is the amount of time in years it takes for you to double your current skin tube length. I'd say based on what I've seen this is something like 3-7 years on average. It took me very roughly 5. Note this is probably a gaussian curve, someone incredibly fast could have it much lower than the average like 2.

How to use: Estimate how much outer skin you need to have to be finished restoring and divide that value by how much skin you currently have e.g.: goal: 9cm / current: 5cm. Then put that value into the above formula and use either your own time_to_double_length estimate or the estimated average value given above:

required_time = 5 years*log2(9cm/5cm) ~ 4.2 years of active tugging.

Someone at the end of a long road or with an incredibly good start could have:

5 years*log2(9cm/7cm) ~ 1.8 years of active tugging.

Someone having a CI-1 start and needing to triple the amount of outer skin could have:

5 years*log2(9cm/3cm) ~ 7.9 years of active tugging.

How the above formula was derived:

The exponential growth equation satisfies the initial assumption:

x(t) = a * b ^ (t /

where a is the initial value of x and the constant

Then we apply it to the current problem.

goal_skin_tube_length = current_length * 2^(t / time_to_double_length) =>

t (in years) = time_to_double_length (in years) * log2(goal_skin_tube_length / current_length)

Additionally:

For a more complete estimate one needs to estimate the required time for both inner skin and outer skin separately.

To get a personal estimate on the time_to_double_length, one can use the first formula if you have two measured length values, or their ratio like 2x, plus the time in years it took in between.

The initial assumption means that if you manage to double your skin tube length you will progress twice faster at that point compared to when you started because you have double the amount of skin cells that undergo further mitosis. To have that speed increase one has to tug all of the available skin in the tube with equal dedication.

I'd like also some other opinions or a more scientific approach to estimate how long it takes one to double one's current skin tube length.
