I wanna talk about normal people with disproportional body. We (the short people) want to become taller with proportional body and that not exist (except jf you have short legs to your body). so we choose to reduce our goal depend on the mokup we do (* i don't think the mokup gives you the right image to your body after lenthening). There is a lot of normal people with disproportional body. Just google these topics and you will understand:
(i have long inseam)
(i have short torso)
(i have small sitting height)
you will find people with their measurements and height.
From my reality, i have a friend (179cm) his legs are 16cm longer than mine (i am 166). He wear upper-cloths size small and some time xs (in European size). His sitting height is exactly like mine and we both have flatt ass.
The right man in this has lenthened 21 cm.!! From 158cm to 179cm!!
http://imgur.com/a/HaqsR5HI didn't know until they told me(livelifetaller) and show his videos. Most of us didn't know about something called proportion until we come here. I don't mean that you can lenthen what ever you want like Apo but you can be disproportional in reasonable terms. The only thing that makes Aop looks very wierd because his small head and his wrong clothes (if he had a bigger head and god clothes he will be normaly disproportional man).
Also you can go to (
https://bodyvisualizer.com/) and make a reasonable mokup (except head and arms you can see how your legs to your looks like after lenthening).
For me my goal is 14cm.
