Data analysis.
I should have kept better records, but this is what I do have. From 3/7/2017-7/21/2017 the measure of Max stretched length in the extender went from ~17.25CM to 21CM.
At that point based on readings here I stopped measuring and only recorded additions to the extender length.
From 7/21/2017 to 12/13/2017 we added 1/2” to the extender length or a rate of ~ 1/4” per 3 months and this pretty clearly marked the end of the newbie gains. These newbie gains IMO were out sized because I was regaining age related loss of length.
I don’t know if the graph above is showing up but from 12/13/2017 to present I have added length to the extender at a rate of 1/8” per 3 months with a slight acceleration the last 6 months, but certainly the graph shows no diminishing returns to this point. I really figured that the rate of gains would decelerate by now.
It could be that it is happening and that the rate of gain is actually greater than 1/8” / 3 months and so the smaller additions are hiding the deceleration but even if that where the case at 18 months the deceleration has to be very, very slow to not show up in the data to this point.
A couple things that I have observed that are out there is the 2000 hour mark and the 2” addition mark.
I’m at 820 hours to this point so I’m not even close to the 2000 hour point where there is some anecdotal evidence of diminishing returns. But this is very hard to validate, because at that point many are adding girth work and if they have been successful which almost certainly they are to have persisted that far, might be satisfied and lose enthusiasm.
I’m at 1-3/8” of extender additions post newbie gains. Statistically there seems to be a fall of gains at the nominal point of ~ 2”. But causality is uncertain. Is there a fall off because of diminishing returns and so the juice isn’t worth the squeeze? Or is it that the gains are sufficient or problematic even and so that explains the fall off?
Admittedly I may not stay in it long enough to be able to answer these questions fully for myself. But this is definitely an interesting part of the journey.
