Why do you mean by chances? How much you can lengthen based on your flexibility?Let's suppose one is not flexible enough to lengthen much, they train for months and their flexibility improve and then they're able to lengthen more, right? Isn't it the point whole point of training, improving muscle mass and flexibility?
Actually, it turns out flexibility is one of those rare things that make lengthening less painful. It's not because you can bend in all kinds of angles, but because your collagen is more 'elastic'. So as you stretch taller, you suffer less soft tissue pains. I didn't have stretching pains until past 7cm, then it started to get tight (even my skin felt like a balloon about to explode).
Of my 7 classmates, 5 stopped earlier than their goal because they could not withstand the stretching pains. I was told it's like when you go through puberty and grow tall over a very short period of time. Literally, your soft tissue and bone hurt from being pulled apart.
Also, from a dynamic point of view, I was able to recover my knee/hip flexion and extensions better, so it meant less discomfort and pain as I can start walking normally, bend my knees in cars, kneel, etc. For some of the guys, it can take over a year to slowly regain flexibility. So pain can come from IT band, hamstrings and other muscles, that are 'shorter' than your new height, so it hurts when you stretch out your leg and take a proper step (not merely just hopping on a walking frame or crutch). So, because of these 'shorter' muscles, less flexible people usually suffer from lordosis or duck ass right after lengthening and it takes specific stretching exercises like the superman pose to stretch out your muscles so that it doesn't make your ass jut out.
But here's the catch, flexibility cannot be trained overnight, not in one or three months even. It's usually years of yoga practice or you're born with hypermobility like I was. That's why Guichet's pre-op training has a big stretching component to it which focuses mainly on your quads and hamstrings. It's just as important if not more than strength training.
Once Guichet measures your flexibility, he can roughly give you an idea of how far you can lengthen before you hit pain. He's not going to stop you from your desired height, but he's realistic. I wanted 7-8cm, and he suggested 10cm because I'm a circus freak. Most guys got about 5cm and Guichet's very good at pushing for more if he thinks your body can handle it. He has good spidey senses when it comes to that.
But the biggest traumatic components about lengthening with Guichet is the post op period (surgery recovery - mental and physical shock of being crippled overnight - it's pretty invasive), hitting stretching pains about post 4cm and flexibility recovery (because when you walk normally, a lot of elements are actually coordinated and these get reset to zero after lengthening - non existent glutes, short IT bands, tight hamstrings and quads, weak abs - all the power force behind a walk, that we so take for granted
