Does Size in the Cylinder correlate to Erection size

Hello,

I am a newbie here and I have been reading various posts in this Forum and I have learned a lot.

My question is Can you count on having a Size increase outside of the Cylinder compared to
Seeing size gains while inside the Cylinder ?

I am not expecting the size outside to match the size while in the Cylinder.

For example. I have made markings on the Cylinder to help chart progress at least for length.
I have seen about 3/8 ” increase in length after 4 weeks when inside the Cylinder.
Does that mean I should see a similar increase in length for my natural Erections ?
I think charting the length gains in the cylinder (at a standard pressure) is more
Accurate than measuring Natural Erections which can vary for a variety of reasons.

I am trying to see if I am making good progress. Your thoughts ?

Thanks

I don’t think you can expect a 1:1 match (inside to outside). But in a broad sense, if size increases inside, it increases outside.

My personal exp, in the beginning I had a good and proportional increase in and out. About the same ratio.

But lately I’m still gaining in the tube but not outside it.
